Finally sorted it out.
Rick kindly used my data on his pc but couldn’t replicate it.
I still don’t know what caused the problem but thanks to a tip from Rick I rebooted my PC and reset PixInsight holding CTRL and pressing R. When I started it back up it worked straight away on default settings.
Still working on my image but I thought I’d write this in case anyone else ever has the same problem and reads this.
Sadly there’s been too much done to my current image for it to work on that so I need to start again.
