Had a weird thing happen last night. I was running a QHY5iii715C camera and everything was per normal until I tried an autofocus run. All of the autofocus frames where blank/ pure white. I've never seen that before so I'm wondering what the cause might be. I was running HocusFocus and checked everything I could think of in NINA to no avail. I'm wondering if anyone else has seen this issue and what you did to fix it.

I’ve had this happen a couple times, one was atmospheric and the other hardware. I’ve had a cloud pass through the frame and it caused the sub to be white/green and I’ve had my usb cable for my camera go bad and produce black or white frames. The usb cable issue was resolved when I replaced it.
Concise
Well, there weren't any clouds and I don't think it was the cable because I didn't have any problems with imaging both before and after trying the autofocus run. In fact, other than that, the night was flawless. I repeated the process a few times with the same result. I thought it might be a camera gain setting somewhere because I change my cameras around often but I couldn't find anything.

Interesting, so you were able to repeat the issue in a non-imaging session? Have you uninstalled and reinstalled the ASCOM driver for the camera?

I was able to repeat the issue during the imaging session. I've not messed with the drivers yet but that will be the next thing.
Autofocus has its own gain settings. I'd just double check there first.

That was the first thing I looked at and it gives exp. time which was normal, nothing about gain though, I don't use filter offsets. If it happens again I'll check min and max to see if there's even any data there.
Well, it worked fine last night so who knows what caused it. Just one of those intermittent software hiccups that are all to common.

Glad to hear things went well. A strange hiccup no doubt.
