Brave Browser keeps crashing itself and other apps via Memory

Description of the issue:
Brave browser often just hangs. Doesn’t matter if I’m using it or if it is idling.
Usually I can close Brave via task manager and restart it. It will work for a while.
Sometimes it crashes after a minute or so. Sometimes after a few hours.

Not always, but in many cases I also get (memory) errors from other applications that suffer from Brave Freezing. Especially Steam and the Signal Desktop app are affected a lot (sometimes I also get a message from a security thing in windows or other apps, but it’s usually Signal or Steam - In case of steam it usually gives a message that the SteamWebHelper is crashed).

How can this issue be reproduced?
It can not. It happens at random.

Expected result:
Brave working stable.

Brave Version( check About Brave):
v1.61.116 - 64 bits

Additional Information:
Tried to clear browser cache. This usually works for about half a day before things go wrong again.

Disabled Hardware acceleration.

Brave is running very stable on other systems. All systems are synced with each other.

Did a Memtest to check if my memory is OK: It is.

Any help here? Or am I just to delete the broser and switch to Firefox?

Same issue here… Here it happens when any brave shows any dialog, like confirm, or add favorite

Not the case for me. Sometimes it even happens when Idling.
