Yesterday I upgraded Visual Studio 2022 from 17.1.x to 17.2. Now, when I try to open a solution, I can see the the Solution Explorer being populated with the projects, and files I had open previously are opened as well. After a second or so, the solution closes.
This happens with most, but not all solutions, but I haven't been able to find a pattern. There was one I that could finally open once, but today it closes immediately again. When I create a new solution and add a project, VS will also (sometimes) close the solution.
What I tried (but didn't fix the problem):
- Run VS in safe mode, i.e.
devenv /SafeMode - Reset VS, i.e.
devenv /ResetSettings - Repair the installation using Visual Studio Installer
- Removed some extensions. Admittedly, I may have to remove all to be sure the rpoblem is not with any of those
- Run VS with logging. The logfile shows some errors about not being able to load ChromeDebugAdapter and EdgeDebugAdapter, but I have no idea how to fix those. The exact error message is below.
Anyone have an idea on how to proceed?
Update My problem seems to be the same as this one. I'll monitor that thread, and post an answer here if it is fixed.
