Long freeze on stage file

[ForNeVeR]

Today, I've been staging some PowerShell files in Git via Rider (I have Git staging area enabled, but not sure how important that is), and Rider's been frozen for about 14 seconds.

Seemingly, the issue is in Git which have been doing some synchronous processing of files, which triggered (and… crashed?) PowerShell LSP server. I'll attach the relevant segment of the logs, and attach the freeze dumps.

dump+logs.zip

I wasn't able to reproduce the issue for a second time, but still: if it's possible to somehow circumvent this in the plugin code (say, not do synchronous reconnection to LSP on a document change), it would be good (and if not, feel free to close the issue; I don't mind).

The freeze stack trace is:
