Another thing that comes to mind is that with new Firmware you can use 2x2 binning on PA. While this makes things faster, it also makes stars „smaller“. Maybe too small for the star detection algorithm.
Did you try on 1x1 binning?
Another thing, did you turn on tracking before PA manually? I see it normally is off and with longer exposures star detection can fail.
I use the 2x2 binning and it works fine.
I know, just another wild guess. But there must be a reason since it still seems to work fine for most people. And it seems to be rather specific to your scope/ filtert camera/ mount/ sky combination.
