all tools stuck as hand tool

so I use the newest update of photoshop CC and I'm having a lot of trouble.

for no particular reason, about a week ago, an error message would pop up when I tried to work with layers. I uninstalled and reinstalled (and updated) photoshop and that bug went away. now whenever I use any tool, the icon for that tool will show up, but it only works as the hand tool. I have tried cleaning my spacebar vigorously, but that did nothing. the brush tool with works if I draw a horizontal line, but that is it. I have reset all tools and restarted my windows 10 laptop countless times.

I use photoshop for art and animation and occasionally simple projects for school- things that could be make in MS Word

I am not an advanced user, and I've been using photoshop for a year.

please help???
