(funny, kind of) Today on a different computer, my own instructions did not succeed.  
Debian-12, Python3.10.15 from conda, prereq as above, everything installed by just pip, building very long for the wheels. Psychopy is version 2024.2.1  
But then, same behaviour as @kbmcgowan 's initial description, no builder-, coder-, runner-windows open.

Solution (following a hint from Jon for Mac [here](https://discourse.psychopy.org/t/psychopy-crashes-immediately-upon-launching-it-on-imac-apple-m3-macos-sequoia-15/42295/22) : kill the hourglass with `Ctrl-C`, change lastFrame to “coder” in `~/.psychopy3/appData.cfg` (deleting the tree did not help). Then _psychopy_ did show the coder window, and switching windows worked.
