I’m tinkering with Slowroll as I hope for it to become my next daily driver. However, I ran into this exact issue too. I suppose it’s not a big deal, because Blender still runs fine with their own packaged .tar.zx v4.5.3 LTS version from their official site - Download — Blender.
However, as I understand, Slowroll will be locked it with this broken version for a month? If so, I really hate to say it, but it’s kind of an L for Slowroll and it’s main purpose
