v1.7.3 seemingly breaks CRT support via RGB-Pi 2

[coderkind]

I updated via the OS to the latest version, and when I reconnected my Raspberry Pi 5 4GB (running off a Sandisk 128GB Micro SD card) via my RGB-Pi 2 it would no longer register a signal. My CRT monitor temporarily flickers during boot-up (like it realises a signal is being sent to it shortly after the 2nd fan noise of the Pi5), but it doesn't render an image.

I'm able to connect fine over HDMI.

I've got the OS set to auto-detect HDMI/CRT, and have CRT set to 15Khz.

I've got two RGB-Pi 2 devices, and tried them alternatively and both at the same time. I've got the OS set to only output to one display however.

I haven't tried flashing v1.7.0 back to the Pi5 because it looks like the official website links through to a Pateron post with a v1.6.0 download?

Definitely, the system works fine with RGB-Pi 2 and any other DAC. I use the same setup myself, and many others are using it successfully with the latest update.
Download the image and update it again via OTA.
