I can confirm that disabling the "OPC Studio" extension in VS 2022 does indeed allow GitHub Copilot to function properly.

The only problem is that the OPC Studio toolbox items are no longer available.

I can confirm the same issue. No problem on old computer configuration but as I've been configuring a new computer I faced the same issue after installation of OPC Studio extension. If I disable this extension no more error. I tried to uninstall and reinstall extension - no luck, still getting this error making Copilot crash:

The 'ConversationsPackage' package did not load correctly.

The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:\Users\mnowok\AppData\Roaming\Microsoft\VisualStudio\17.0_17c09894\ActivityLog.xml'.

Restarting Visual Studio could help resolve this issue.

Hello.

For start, please check whether the OPC Studio extension for Visual Studio is still installed, and if so, uninstall it: See  opclabs.doc-that.com/files/onlinedocs/OPCLabs-OpcStudio/Late...sual%20Studio%20Extension.html .

The Visual Studio is the only way the OPC Studio can "permanently" affect how Visual Studio behaves.

Best regards

OPC Studio breaks Gitub Copilot in VS 2022 was created by jgyenese
I have been trying to track down a problem with Github Copilot not working, and I traced the issue to OPC Studio.  I have reproduced the issue using the following steps.

1.  I started with a fresh install of Windows 11 Pro and used Windows Update to install all updates.  Windows version is 24H2.
2.  Install Visual Studio 2022 Community with MAUI, .NET Desktop, and WinUI application workloads selected.  Visual Studio version is 17.14.6.
3.  Launch VS and login to Visual Studio and Github accounts - Github copilot is working - green checkmark and chat window working.
4.  Install OPC Studio 2025.1 and accept all of the default options.
5.  Launch VS.  I get the following error message: The 'ConversationsPackage' package did not load correctly.
     Github Copilot not working - no green checkmark and chat windows says "Something went wrong.  We're sorry, the Github Copilot service is temporarily unavailable."

Uninstalling OPC Studio does NOT fix the Github Copilot problem.

Any help would be greatly appreciated.
