I've left it starting up, but I've got a couple of comments...
Having selected the [x] Start Mu checkbox, I had to wait something like 10 seconds before anything appeared. I'd actually started running Task Manager to see if it was running before the splash screen popped up.
The splash screen is too big for my 14" laptop screen. I took a screen snip which I'll drop here in a mo. But the long and short is that, while you can see the animated snake, you can't see any of the info log underneath!
Just read the changelog from Merry Old "Saint" Nicholas š
Although I actually created the trivial PR #1921, we should credit https://github.com/hmmkay who actually analysed the problem and proposed the solution.

folder or the venv itself twice at the same time?
