Seeing this error occasionally. Any fix can be applied?

Unfortunately I also experience this problem.

A comment on this one:

I have a test program that I can run a few hundred times before the error appears.

However, if I replaced the NuGet package, by downloading the source code (and upgraded the project to .net 4.8), and recompiled, I can run the same test program 15000 times without seeing the issue.
I'm not 100% sure why (I did not make any code changes) but the problem does not appear anymore.
