Updated Vital and Now It Wont Open

Hey all, I installed Vital - 1.5.5 after downloading some themes and presets and realizing I couldn’t run them on my older version. However, now I can’t open Vital at all. It opens for a split second then immediately closes again. I’ve already uninstalled and installed it multiple times. Vital was working perfectly fine beforehand, how do I fix this issue?
Thank you

Have you tried renaming your default preset and/or config file?
