Audio Track stop randomly after freeze

Just wanted to freeze my guitar tracks with Helix Native on them while working on other stuff in the project but after freezing, the tracks just stop at random points. This problem only occures on some tracks, like the four rythm guitars and always towards the end of the song. Other tracks like bass or guitar layers with the same plugin work perfectly fine.
I first thought it was just a simple error during freezing but when I tried to freeze them again I found that each track stopped at roughly the same place as before and the linked channels also always end quite close to each other.
Has anybody had any similar problems and found a solution?
I’m currently at Cubase 12.0.70 an tried with both HX Nativ 3.70 and 3.71
