Why It''s Showing just a white page to me

[AmirZ93]

I just can see a white and empty page. Help me

[InukaAsith]

re install
restart the app and device

ui is not rendered within the app
maybe antivirus deleted some components while loading (not yet signed so some antivirus can delete unsigned executables)

I did it, But it wasn't work.
I re installed the app and I restarted my device, But it wasn't work.
I ran it as adminstator, But it also didn't work.
What should I do?
