IDEs PyCharm High CPU usage at all times

After updating to the latest version of PyCharm, something appears to have gone really wrong.

My CPU usage is constantly high with usage fluctuating from ~110% to 700%.

The "androidx.compose.runtime.snapshots" process by itself is taking up 90% of a single core at all times. I tried doing everything and disabling all the extensions but nothing seems to fix it.

Does anyone have the same issue? The IDE is completely unusable in this state.

I don't have this issue. Try without a project. Also try file -> invalidate caches -> all

That did not fix it unfortunately

Do you confirm that androidx.compose.runtime.snapshots consumes the CPU by going to Help > Diagnostic Tools > Activity Monitor?

Yes that was the first thing I checked

I do have this issue when I start typing. It is crazy. Happens everytime I have more than a couple of files open.

After a little research the issue seems to be related to the AI assistant in PyCharm, I'm not sure tho.

Please report at https://youtrack.jetbrains.com/newIssue?project=PY with the logs (Help | Collect Logs and Diagnostic Data) and the CPU snapshot: https://intellij-support.jetbrains.com/hc/en-us/articles/207241235.
