When playing in the genesys preset (specifically, with the extra game rule “Show Extra Monster Zone” deactivated), if your 5 monster zones are full, and you have 2 monsters in the spell / trap zone, you can begin to summon Snake-Eyes Doomed Dragon, but because you don’t a zone to summon it to (the EMZ doesn’t exist in Genesys mode), you can’t finish the summon and you’re soft locked.
Screenshots of the bug happenning:
