We have exactely the same problem and it is 100% reproducable on any hardware running W1123H2.
(Windows 10 is not affected)
Creative Cloud Desktop App 6.4 is installing PxHlpa64.sys into C.\windows\system32\drivers and this driver ist marked as incompatible with Windows 11 Memory Integrity.
The next reboot will be your last one, since you get stuck in a BSOD.
There are 2 workarounds: disable Windows Memory Integrity (which should be enabled by default!) or delete PxHlpa64.sys.
This needs to be fixed immediatly!
