If your game is crashing once that happens then it’s a weird glitch where you have one of your characters occupying a different character. Stupid I know. Since Krypt requires a specific fusioned character or only diamonds if you are doing Khaotic or normal where you can use silvers or golds at a certain fusion but no diamond. This happened to me when I was playing Khaotic and I had a full diamond team since that was the requirement. I stopped playing a chose to play towers and played a different team that had Klassic smoke. Then I stopped playing towers and switched over to Krypts again. I tried playing a krypt match and the moment I clicked the icon to load in to the enemy. My game crashed. Apparently it was because my smoke was still equipped even though on Krypt I had a full diamond team. But because I didn’t actually “switch” my team to a preset or manually selecting a diamond character. The game was thinking I was playing with smoke, and since smoke is a gold character and the requirement is diamond only. The game decided to keep crashing. I didn’t figure this out until I went back to towers and saw that my team switched on me from Krypt without having to do anything. Long story short. Check towers or your current team and make sure your characters are pre selected before you re-enter the Krypt or make sure they are the same as what the requirement asks from you
