Do you mean version 2026.1.3 right? 2026.3 is not yet launched. Either way the PotemkinOverlayProgress freeze is separate from the earlier memory one. The UI is stuck waiting on a background indexing task that's blocked reading a file from disk (file-type detection). On Windows it's almost always antivirus scanning files or the project sitting on a slow/network/cloud-synced drive.
Worth trying:
- Add antivirus/Defender exclusions for the project folder, your virtualenvs, and the PyCharm config/system/plugins folders.
- If the project is on a network, WSL, or synced drive (OneDrive/Dropbox), move it to a local SSD.
Ooops … 2025.3
Double-check on the latest 2026.1.2 for PyCharm – we made several performance improvements on that version.
