Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.

I have a similar problem. My MacBook has been crashing when I try to load Zwift. As the program loads, the screen glitches and the computer freezes. Sometimes it will restart on its own but other times I have to press the start button to reboot. I thought this issue was related to the Zwift program but it happened again today while trying to scan photos. This laptop has been very reliable up until this problem. It’s an early 2015 MacBook, 12-inch, Catalina 10.15.4.

Could a stuck key cause this?

Not likely a stuck key.
