Body

I am using Rider for windows (latest version) and the latest version of the plugin.
Only the chat window (luckily) stopped working, but there is no way to make it work again. I get these exceptions

Unhandled exception in [ComponentManager(ProjectImpl@1097189798), CoroutineName(com.intellij.openapi.wm.impl.ToolWindowManagerImpl), ModalityState.NON_MODAL, Dispatchers.EDT]

I of course tried everything was possible to try. The only doubt is the fact that I sync the settings and so even after I uninstall and nuke everything, most of the settings are set back to what there were.

It sounds like you’re encountering an issue with GitHub Copilot’s integration in Rider, specifically with the chat window feature. Since you’ve tried a lot of solutions already, here are some additional steps you can try to resolve this issue:

1. Update Everything

   • Rider: Ensure that you’re using the latest version of Rider. Occasionally, plugin compatibility issues arise with IDE updates, so double-check that Rider is up to date.
   • Copilot Plugin: Reinstall the Copilot plugin to ensure you’re using the latest version.
   • Java JDK: Rider relies on Java, so make sure your JDK is updated, especially if Rider uses the system JDK.

2. Clear Plugin Cache

   • Go to File > Invalidate Caches / Restart in Rider.
   • Choose to Invalidate and Restart. This will clear your caches, which might resolve issues with corrupted plugin data.

3. Check Settings Sync

   • Since you mentioned settings sync might be restoring previous configurations, try disabling it temporarily and then uninstalling/reinstalling the plugin. This ensures you’re starting with a fresh setup without old settings interfering.

4. Verify File Type Associations

   • The errors you’re seeing suggest a problem with file type associations. Go to Settings > Editor > File Types, and ensure that all necessary file types are correctly associated with their editors. In particular, make sure that any file types used by the Copilot chat feature are not set to null or have missing associations.

5. Reinstall the Plugin from Scratch

   • Uninstall the Copilot plugin, then manually delete the plugin directory from your Rider plugins directory. Afterward, reinstall it from the plugin marketplace.
   • On Windows, Rider plugins are typically located at:

%USERPROFILE%.IntelliJIdeaXX\config\plugins

6. Check for Known Issues and Workarounds

   • Visit the GitHub Copilot Rider Issues page to see if anyone else is facing similar problems. There may be temporary workarounds or updates from the GitHub team.

7. Report the Issue

   • If none of the above solutions work, consider opening an issue on the GitHub Copilot support page. Include your Rider version, plugin version, Java version, and the stack trace. The developers might provide additional insights or prioritise a fix.

These steps should help you isolate and potentially resolve the issue.

[sebas77]

the link for the issue report doens't work

[erlgr]

I have the same issue, also in Rider (2024.2.5) for Windows (10). Completions don't work, the chat window does. I have tried reinstalling copilot, nothing.

However, this could be a Rider specific issue, as it still works perfectly on IntelliJ, also in the latest version of both the IDE and copilot

quick edit: shift+enter for new line on copilot chat doesn't seem to work on Rider either, but it works perfectly on IntelliJ.

[erlgr]

It seems to work again now! @sebas77 give it another shot :)

[pandamicro]

I can confirm it's still not working on myside, with the same exact exception.

• Rider version: JetBrains Rider 2024.3 (Build #RD-243.21565.191)
• Copilot 1.5.29.7524

Tried to upgrade to 1.5.29.7991 nightly is not fixing it neither

[KrisJelbring]

I have a co-corker that has the exact same issue. I have the same versions installed as him but for me the plugin works fine.

We've tried all the suggestions above to no avail. Any other ideas?

Rider: Build JetBrains Rider 2024.3.3 (#RD-243.22562.250)
Copilot 1.5.30-242

[corne-ac]

Currently have this exact issue also, same error message

Rider: Rider 2024.3.4 (243.23654.126)
Copilot: 1.5.32-242

Nothing has worked, from clearing cache, reinstalling, logging out/in, deleting directory.

[corne-ac]

Fixed mine by deleting all my project files, and cloning my project again (all IDE settings were not part of the project git, so assume when it got re-generated or whatever, it fixed something). The chat window didnt work on only one project.

[Ares9323]

Different error message but same result,
Things I've tried:

• Uninstalling and reinstalling plugin
• Clearing cache
• Logging out/in

Copilot-Chat is working normally, but as soon as I try to use autocomplete I get the following error:

[JasonLandbridge]

Greatly appreciated that you added your fix! This worked for me as well! Thanks 🎉!

[RushilJalal]

Getting a similar error but I don't even use Rider, atleast not that I'm aware of.
I get this error everytime I click on any option on the right sidebar in Android Studio.

I have the issue in one week and resolved issue by reinstall Github Copilot plugin in Rider.
