Hello,
Are there many CIS 8012 users running it with W11 ?
How is it going ?
no problem here, running smoothly
CIS is very smooth on a Win11 upgrade on my Lenovo laptop.
CIS was previously installed under Win10, updated to 8012 under Win10 and then Win10 upgraded to Win11 without an issue (from Win11 or CIS).
Cheers,
Ewen 
No worries on my side 8)
