Vscode 1.101 crashes prettier extension, regression from 1.100.3

[alwin]

Type: Bug

In VS code version 1.101 I get "Extension host terminated unexpectedly 3 times within the last 5 minutes"
Extension bisect points to esbenp.prettier-vscode
When I rollback VS code to 1.100.3 the problem is solved.

VS Code version: Code 1.100.3 (258e40f, 2025-06-02T13:30:54.273Z)
OS version: Windows_NT x64 10.0.26100

I have exact the same problem, but using yarn PnP. I also found this issue: yarnpkg/berry#6805, maybe related.

Thanks, I also use yarn PnP (latest version 4.9.2 and all yarn SDKs updated).

Because I get this bug after VScode update, I think it's a regression in VScode, not yarn. That's why I posted the bug in VScode.
