The Leaks instrument is suddenly giving me the error "Required kernel recording resources are in use by another document." I see this has come up with Xcode 12 on iOS, but now it's happening when profiling a Mac application on Monterey 12.3.1 and Xcode 13.3. I get the same behaviour on a debug or release build. The Allocations instrument on its own also gives the same error. The Time Profiler intrument launches without issue. Regardless of the (useless) error, it's possible this is a signing issue, since Intruments is also constantly asking for a password when launching the process. Does anyone have any insight into what is causing this?

I just upgraded to Big Sur and now I can't resize the navigator pane in Xcode 12.3--a major problem when a project has a directory structure deeper than two levels. Other apps (Finder, Safari) don't seem affected. More information: Not all projects/workspaces are affected. The project that was is one generated using cmake, and re-generating that project has fixed the problem.
