Potentially a new occurrence of #10759, at least the symptoms are the same, but don't know how to reproduce.

This is the only log I got:
[LSP][LanguageServer.Semantic.LSPCSharpSemanticTokensProvider] [21:45:27.3641380] We are behind the C# version which is surprising. Could be an old request that wasn't cancelled, but if not, expect most future requests to fail. We were wanting 251 but C# is at 254.
Reopening the file resets and solves the issue.
