Hi there,
Sorry to hear about Photoshop crashing. I see that you're on Photoshop version 2020, could you try updating Photoshop to version 2021 through the Creative Cloud Desktop app and let us know if that helps?
As you're working on macOS, you may also try the following steps and see how it goes:
Please go to the System Preferences of macOS, then Security and Privacy & select the Privacy tab. Once there, please select Accessibility from the list on the left and add Photoshop to the list by unlocking the window using the lock icon. Also, grant permissions to Photoshop under Full disk access. Once done, restart the computer and let us know if that helps.
Regards,
Sahil
