(2022) Photoshop tools switching to eraser at random

Hello!  I've encountered a bug that is slowing me down a bit in photoshop.  When I am drawing, the tool will switch to eraser at random and erase my work.  I often use hotkeys while drawing, but when this occurs I am not touching any keys.  I use a wacom tablet and thought it may be to blame--until last night when I was working with just my touch pad on some basic photo editing.  The tools I would use (whether brush, select, etc.,) would again switch to eraser at random when I clicked!  Thank you in advance for any help.  I can usually find an answer somehwere, but I haven't seen any forums discussing similar problems.
