I am working on a project in VS targetting .Net5. When I have a particular file open in VS, I get frequent "VS not responding" notices, especially after debugging, code error reporting sometimes stops working, code expansion nodes fail to appear and a few other oddities. If I keep the file closed, there is none of it - everything works OK. Any ideas what might be causing it? The file in question is quite large and contains many controls, but I haven't had these problems before with larger files. Thanks for any help.

Probably one or more extensions causing the slowdown. Run VS in safemode. If the problem goes away it is an extension issue. In newer VS versions it should report if an extension is slowing things down too much. Otherwise you'll need to start disabling your extensions until the problem goes away. Once you've found the extension you can report the issue to the author.
Alternatively you can use Report a Problem in VS directly, replicate the issue and send the report to MS so they can look at it. From there they will either identify an issue in the shell or be able to identify which extension is causing the slowdown.
I wasn't able to run the project in VS safe mode as VS reported that it couldn't open any of the project files, suggesting that they needed to be converted? I then opened the project as normal and disabled all extensions except Intellicode, which apparently has dependencies in the project. After re-starting VS I found that the situation was as before - everything is OK until I open the file in question and then the usual problems start. So, it does look as if the file is somehow at fault. I'll try your suggestion of replicating the issue and reporting it to MS.

Hi mderj,
You can try to disable live share extension, then restart visual studio.
