Problem updating matlab 2020b

I am using 2019b and was offered the option to upgrade to 2020a. However, partly through the upgrade, matlab crashed. I now cannot open matlab. I get the error that code execution cannot proceed because libmwfl.dll was not found and reinstalling would fix this problem. I get 4 errors like this for different files not found. I then tried to uninstall so I could properly reinstall. I ran the uninstall.exe file. It fails because it cannot find MATLAB\R2019b\help\symbolic\helpsearch\segments_g. So I can't uninstall or use matlab right now. What should I do? I'm using Windows 10.

Try just deleting the MATLAB installation directory, which is probably under C:\Program Files\
