Lightroom crashes when browsing through presets

Hi everyone,

for some reason Lightroom keeps crashing when randomly browsing through presets. Speed doesnt really matter in this case. It's always the same: Browsing through it, suddenly it stops reacting.

This just started like two weeks ago.

I've already tried out my other PC - Same problem.

Reinstalled it - Same problem.

Used a previous version - Same problem.

GPU on both PCs is not at 100% neither is the CPU.

Any suggestions on how to fix this?

Thanks,

Dennis
