Why does my screen turin white when trying to access my dashboard?

I’ve tried to access my dashboard to no luck, for some reason it boots up for 2 seconds then just turns white. Has anyone else have this issue? and if you did who did you resolve it?

Make sure any ad blockers are disabled, I’d try turning off other extensions as well.
