Game loads up fine for first player, but when I try to open the second instance it crashes that instance, yet keeps the first player up.

Things I've tried

• computer restart
• changing the TTWL settings in Epic to -> additional code -> -dx11
• Deleting the 3 save files located here: %localappdata%\Tiny Tina's Wonderlands\Saved
• waiting a few minutes after the first instance has fully loaded to try the second

We were able to get it to work last night, but when we exited the game we got a crash notification. Didn't think anything of it. Now, like I said, I can get the first instance loaded up but the second won't load in. Any advice?

If it matters, a few minutes after exiting both instances when I realized it wouldn't work, I got a crash notification from Nucleus of: InvalidOperationException. I just figured this had something to do with the second instance not loading.
