AMDRyzenMasterDriver.sys and Windows Core isolation

I'm using an the HP Pavilion Gaming Laptop 15-ec0xxx

OS: Windows 11 Home, version 10.0.22621 build 22621
Motherboard: HP 86D5 96.45
BIOS version: AMI F.13
CPU: AMD Ryzen 5 3550H with Radeon Vega Mobile Gfx 2.10 GHz
Integrated graphics card: AMD Radeon Vega 8 Graphics
 
Since the update to Windows 11, the desktop background started disappearing (everything works normal, the picture just becomes all black).
I have also started getting lots of LoadLibrary failed with error 126 from AMD Radeon software, during normal use of the PC (while using other software, without even opening AMD Radeon).
(picture is not mine, but this is how the error looks like)(picture is not mine, but this is how the error looks like)
 
When i turn on Windows Core isolation, I get another error on startup. This time about AMDRyzenMasterDriver.sys not loading due to vulnerability issues detected by Windows Core isolation.
sorry for bad qualitysorry for bad quality
 
I have tried to install drivers from this page, both by using the auto-detection software and by selecting the hardware from the list myself.
I have tried to reset Windows 11, even with the re-download mode.
 
None of this has worked. If someone knows what I should do, I would be very greatful!
Thank you!

Any update on this?

Has the core isolation issue been solved in the driver?
