Zoom not opening

[Envoriium]

zoom desktop app wont open 
i mean technically the process itself is running but it says im not signed in and the screen wont pop up at all
it was working fine for 2 yrs until it stopped opening after i clicked some meeting link for my school 3 months ago (june)
ive tried to delete the app files and everything but it didnt work
whenever i try to delete the app with the uninstaller it'll say it failed with error code 3000
i tried using iobit uninstaller and completely delete all of the data and registry and it surprisingly worked until it started to actt up again after a few days

i was going to write this formally  but i dont have much time to write this as i have smth to do
please help me with this issue and thank you for reading
