Hello, on MacVim startup I get this error in the status area:

Copilot: Process exited with status 243

:messages does not output anything else.

:Copilot status, :Copilot setup returns the same error as above.

:Copilot version
copilot.vim 1.59.0
Vim 9.1.1887
Not running
macOS

I did not change anything in settings, plugins or anything else. Problems started a day ago or so.

If you have tips what else I could show you to debug this issue - please tell.

I am enterprise GitHub Copilot user.
