I installed the beta last night and the crashes stopped for a short time, and then started again the next time I tried to change the theme. The main time I experience crashes is when browsing themes or changing a theme. Just found this forum while at work so I can't provide any logs, but can later today if necessary. System specs below:
Dell XPS 15
