error An exception occurred: CLR/System.NullReferenceException after fork sync

[onesch]

Today I synchronized my fork with the local copy and continued working on my tasks, after which I saw that an error began to appear, I thought that I wrote something wrong, but no, in the branch where I conduct my “experiments”, this error also appears in the master branch ( I synchronized these two branches today), well, I think let’s check with the branch that was not synchronized today, it does not crash with this error, everything is ok in it.. why?

• when does the error appear?
  I don’t do anything, I just stand there and after about a minute an error pops up.

An exception occurred: CLR/System.NullReferenceException
Unhandled exception of type 'System.NullReferenceException' in Content.Shared.dll: 'Object reference not set to an instance of an object.'

Seems to be getting fixed #33679
