System fully freezing, must shut down my PC from the power button

Hi and welcome @CoolDoge
It is not recommended to switch off using the power button.
There is a much better way to restart the system shown in the thread. You will find it in the solution at my first post at my thread Restarting -> stop job for user running!

It was a different situation where shutting down was taking ages.
I think/hope doing the REISUB button sequence might help in your case as well.

I hope to hear from someone experienced about these freezes as it happens with me one or two times I don’t know why, and REISUB did the reboot the proper way.
Please let me know.
Thank you.
