I just had the same thing, private personal server 3.9.1 suddenly just wouldn’t start. Not sure how long its been like that, I haven’t used it for a few weeks.
I downloaded 3.11 and extracted all of the files over the existing ones and its starting again.
Nothing obviously useful to me in the logs.

Screech, how did you manage to jump from it doesn’t work on both of his servers to accusations of licence fraud. Trying it on another box is a perfectly reasonable diagnostic step when something stops working. If he is in the market for a commercial solution that sort of nonsense is going to send him elsewhere.
