The DE10-Lite uses the MAX 10 family devices.
Quartus 20.1 supports MAX 10 family, but is not listed as being qualified on Windows 11. So it may work, or not.
According to the OS support page, version Quartus v22.3 or later is qualified for use on Windows 11, and it supports MAX 10.

I don't work for either TerASIC or Intel/Altera.
I do have a DE10-Lite board that I purchased via a distributor for my own personal use.
I can't send you quotes, but you can buy the board thru TerASIC (and get an academic discount)
or various electronics distributors (but most likely you will pay full price).
I suggest you contact TerASIC thru their website at the link I posted previously.
You can also download all the support files (examples, user manual, etc) from their website.
