Right. I had a similar issue last year with ONE of my windows 11 machines, see this post:
When in normal mode, do you also get that popup error regarding the netsh.exe application ?
Note that you might have other issues with running SGP in admin mode, difficulties connecting to some gear etc, so be aware of that.
On my windows 11 laptop on which I developed the Collimation Aid I have had none of these issues…
