PyCharm 2026.1.2 is a hot mess
I don't even know where to start with submitting issues so i'm starting here first.
I'm on 2026.1.2 for ARM64 and as soon as I upgraded, so many things broke.
- selecting a WSL interpreter that I know has packages installed just shows “Nothing to show”
- startup takes so much longer
- debugging takes forever to start
- there's a browser preview on the right side that I don't want and can't close
- “waiting for process detach” rarely finishes and I have to manually go kill a process
- starting or restarting a run configuration takes literally a minute or more, and there's no option to kill the process
Invalidating caches fixes nothing.
I can't be the only one having these issues, but I'm not finding any results when I search?

Hello, @Harveynr,
The issue indeed requires investigation. Please create YouTrack ticket and attach a log archive, which can be found under Help | Collect Logs and Diagnostic Data.
@Deadshot IO
this is most likely a PyCharm 2026.1.2 regression/compatibility issue involving WSL and/or the ARM64 environment, and the symptoms are substantial enough to warrant an official JetBrains bug report.

Great write-up. Posts like this are genuinely useful because you didn't just say the update is broken, you explained exactly what changed and what you've already tried. The “Nothing to show” issue with a WSL interpreter sounds particularly strange. Thanks for taking the time to put all these details together.
