CTD When disabling transparency after enabling emission

- System setup (GPU, CPU, OS version, Blender version)
Win11, Vega64, xeon e5 2696v4, blender 3.5.0, RPR 3.5.15
Enterprise driver 22.Q4
Blend file attached:
SingleBulb.zip
Issue
On this specific blend file, if you enable emission on the "Bulb Glass" material, and then disable transparency right after, blender crashes to desktop with no errors in the console/log
Steps to Reproduce
Open blend file
Enable Emission on the rpr uber node on "Bulb Glass"
Disable Transparency on the same node
Wait a few seconds
Crash.
The Viewport can be in any mode, it even happens in "Solid" view
This occurs with both cpu only and gpu only rendering, and doesnt occur in interactive mode.
As a further oddity, before blender crashes out, it seems like it creates an infinite loop on the gpu. The gpu usage goes up to 100%, as well as the clocks all go to 100% without any noticeably increased memory usage, and the power draw only goes up to about 50w, when 100% usage equates to 150-250w
