I wasn't able to repro the crash exactly, but there were issues with lagging and shaders I believe it was related to. I have made a few changes, tested myself, and uploaded the new builds. Thank you again reaching out with this.
Awesome, thanks for fixing that! I actually just posted the video from that run where I hit the ending, though continuing on to hunt for more anomalies is what finally crashed it. Excited to try the new build!
