I tried these versions (20.04.4, 20.10, 21.10) from ubuntu with the above PC setup and my second PC setup.
I tried it even with a normal HDD.

I cannot install ubuntu for both PC setups.

Second PC setup:
Installation type: via USB flash drive
CPU: AMD Ryzen 7 3700X
RAM: 32 GB DDR4 (2x 16GB - NO ECC)
Mainboard: MSI X570 Gaming Plus
Installation drive: Intenso M.2 SSD TOP (256GB)

I think it looks like an AMD Ryzen issue to me...

With Fedora 35 there where no issues at the installation process at both systems.
With Windows 10 also there where no issues at the installation process at both systems.

Ok seems that Fedora 35 also got a problem.
After creating the user and "Start Using Fedora" the system does not show "Activities" and the top navbar clock. I only can navigate to network, audio and power controls.
Mouse does work. Keyboard-Shortcuts don't work.

At Windows 10 there was all fine.

Status changed to 'Confirmed' because the bug affects multiple users.
