RB2019 and 2021 both run as Admin, both deleted and re-installed.
Intel Core i7-6500u up to 3.1GHz, 12GB RAM

RB is known to be a bit unstable, but lately, for me, it has reached ridiculous levels, freezing or closing suddenly several times during a session. Only very rarely can I complete a session without interruption.
I don't think this is 2021 related since I mainly use 2019 for 32bit, and nobody else has reported anything like this.
I've narrowed it down to beginning to occur after a Win10 update in early December and reckon, in the absence of any other reports, that the problem is with my laptop.
Any advice or suggestions will be gratefully received.
