Crashes while launching Zwift

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 power button to reboot. I thought this issue was related to the Zwift program but it happened again recently while trying to scan photos. It has also happened in Safari. This laptop has been very reliable up until lately. It’s an early 2015 MacBook, 12-inch, Catalina 10.15.4.

Sometimes, while restarting, the computer will present a dialog that says something like "Your computer is restarting. If you'd like it to restart and open the same programs that were running before press okay otherwise do nothing and it will restart in 30 seconds." If I press okay, it's likely that the computer will crash again once restarted. If I press "cancel" the computer will start up normally.

Could a stuck key cause this? I've recently noticed that my right shift key is sticking.
