I'm not sure what's causing this, but this specific log caught my attention:

thread 'Worker' panicked at C:\Users\runneradmin\.cargo\registry\src\index.crates.io-1949cf8c6b5b557f\salsa-0.20.0\src\function\backdate.rs:31:17:
assertion failed: old_memo.revisions.changed_at <= revisions.changed_at

Did I mess something up? Or this is salsa issue?
If I opened my lib.rs it's just loading till panicked. It's also taking up huge amount of memory.

Any leads / helps appreciated, thanks!

variances_of_shim

Likely a fixpoint bug

Getting a similar crash.

Curious if anyone has found a workaround for this. It's completely borked rust-analyzer for me. I've tried uninstalling and re-installing the extension, but wondering if there's some kind of cache somewhere I can bust

[Veykril]

for now you need to go back to last week's release. We will likely roll back the change for this before next monday for the time being.
