Can't launch a game

I ran a game last night (Friday) without any problems but today (Saturday) when I went to work on an upcoming game and saw an odd message that Roll20 had to unpack my game or un-archive it (not sure, it went by quickly) and since then I can't launch any of my games, they freeze up after going to the black loading screen.  I am using Firefox. I cleared the cache in this computer. I can launch the games using MS Edge on my main computer or Firefox on my other computer, but I really need it to run on my main computer .  Anyone know how to fix this?

Im experiencing the same problem!

Hi folks,  You could try to use a Private (Firefox) or Incognito (Chrome) window. If that doesn't work you might try clearing cookies/cache.  Of course, if neither of those work your best bet is to file a bug report with the Devs via the Help Center as the forums are primarily users helping users.
