After Enroll MOK during instalation Cuda- stacking at black screen

I downloaded Installer for Linux Ubuntu 22.04 x86_64, then i made all instructions from Base Installer:
Installation Instructions:

Then appears Configuring Secure Boot, which says to “Enroll MOK” and “Change Secure Boot state”.
I wrote new pass and reboot computer. At blue menu i choose Enroll MOK, press enter, and after rebooting i see only black screen… I can go to bios and grub, but ubuntu doesnt load…
How fix that?

Probably known driver bug:
Same as 515.76
