I've had MC Dungeons since release. when i started it everything went as usual up to this white window (image). I closed it and then nothing happened. let it run for 20 minutes (image 2)
I followed the instructions of the support and again it didn't work. I uninstalled dungeons, waited a day and reinstalled them, to no avail.
I did the same with the launcher without success.VPN disabled without success. This white window always appears and then nothing happens. I almost suspect that the migration of my mojang account deleted or damaged the purchase info. the receipts are gone too.
