SourceTree Performance on MacOS is Very Poor

[Jonathan]

I have been using SourceTree as a git client for numerous years at this point. For some reason, the performance of the software on one of my computers has gotten frustratingly bad. I'm on the latest version, have tried reinstalling, switching between using system/sourcetree git, etc. with no improvements. I have SourceTree installed on another computer of mine and it works perfectly fine. Adding files to be committed, pushing changes to remote, etc. all take at minimum 10+ seconds. Every other computer I've used it on executes those commands in maybe a couple seconds at most. 

Is there some way that I can 100% reset SourceTree on my computer so that I can regain performance?
