Manjaro keeps blacking my screen forcing me to restart, nothing seems to help, It's making me go crazy!

You have this issue too?
What’s the result of inxi -SCGM for you?
What’s your monitor model?

We might get this to the Linux kernel devs.

[update]

I now have an extra issue, because a setup requires me to use Linux 5.10.

$ docker run --runtime=sysbox-runc -it dockerfile
docker: Error response from daemon: failed to create shim: OCI runtime create failed: kernel version check failed: manjaro kernel release 5.4.135-1-MANJARO is not supported; need >= 5.5: unknown.
