Various dark mode extensions are also known to cause this issue.
If that doesn't help contact support ([email protected] or discord.gg/monkeytype) If the website works for a bit but then this screen comes back, clear your cache again and then on Monkeytype open the command line (esc) and search for "Clear SW cache".
