Can log in on MathWorks website, cant in the MATLAB app on windows

My problem started when I needed to use a addon that i didnt have, 'signal processing toolbox'.

when I tried to click 'get addons' I just got a whole bunch of errors (shown below)

I tried to reset my preferences but no dice.

So I googled and it just told me to reinstall MATLAB.

when I tried to do that it said i had an incorrect password.

I know my password is correct because I can log in with it in MathWorks.com (hence me being here)

I tried to reset my password but the same thing occurs, I can log in fine on here with my new password, but the MATLAB installer just says it is incorrect and locks me out of trying

Im on windows, with version 2021b

also, I tried to call support on 508-647-7000 but that number was not in use.

Try renaming your flip.m script file located in:

C:\Users\jonat\OneDrive\Documents\MATLAB\flip.m

Its existence prevents MATLAB from calling the flip function included in MATLAB.
