I used dd. Something like "sudo dd bs=4M if=/image/to/iso of/dev/sdX oflag=sync status=progress". Burning the original iso the same way had no issues.
I still have the project folders. In fact I have three of them, since I initially thought I was editing something that was causing problems, so I made a few different tests, and even without any changes, it gives the same problem.
I managed to edit a ubuntu 18 image and boot into the live desktop without any problems.
