Lately my MBP is repeatedly crashing (every few minutes) when watching Netflix content through Safari.
Screen will turn dark with no sound; keyboard will light up as if locked but unlocking via Touch ID has no result. Only option is to hold power key until Mac shuts down and reboot.

MBP is running 10.13.6 (latest version of High Sierra). I cannot recall this happening under 10.13.5 but I am. not sure what is the culprit.

Only thing I am aware that has changed since I watched previously on MBP is that I installed Malwarebytes, however, not the paid version, no "real time" protection.

Etrecheck did not provide any insights ether. See respective section here:

Anybody any ideas what is happening here?
