Then it's something else. If you can upload log.txt from that exact folder after crash it might help. I assume it crashes before frontend even initializes.I have the lastest version and trying to update it or reinstall it doesnt change the outcome unfortunately, neither does settings the true values to false.
In the meantime go to ck3toeu4 folder. Inside copy configuration-example.txt to configuration.txt. then edit it manually to set the paths and options (i don't recall if I put config selections on wiki) and start the backend itself. Once it's done the mod will be in output folder.
