Hi. Was having same problem on Windows 10.

Restarting of PC, deleting cache, etc didn't help.

Neither disabling notification, origin in-game, focus assistant, updating driver, etc... 

So I run cmd and type below commands:

chkdsk /f /r 

sfc /scannow

Just to see if there is problem with windows.

Then I uninstall Origin and go to my network and do Network Reset (not sure if this was the problem, but I just did)

After that PC restarts.

After PC was back on I download origin client again.

Install it and then verified FIFA20.

Run the game and it was running smoothly without any interruption.

Hopefully somebody will be lucky with above steps.
