Contributing my grain of sand:
Some weeks before I installed SVP in a W11 beta version and it didn't work, it gave me 2 error boxes before the end of the installation.
Today I installed SVP in the stable W11 version (clean) and it works. What I find different is that in W10 I could play movies in 120 fps and it used to work really good (high cpu usage but understandable). In W11 if I go past 60 fps it starts to give me some stutter (unwatchable). I don't know if the problem is SVP or W11 but it is how I'm now.
Anyway I'm happy that it works.
