The first attached screen shot shows a consistent result this evening when I have turned on soft proofing and then when I click the red "X" to switch it off. The only way to recover is to close the program. Fortunately so far it has closed without further crashes. This has never happened before tonight.
Knowing that soft proofing is actually comparing the Monitor Profile to the Printer profile, we must have a look at the two profiles you chose for those positions.
I caught a glimpse of an ADOBE RGB profile in the printer profile box. That, to the best of my knowledge, is not a printer profile.
I have no idea what is in the monitor profile box.
Naturally, it should not have crashed, and I'm sure Mike will want to check it out if it happens again.
If you can create the crash, please present as much detail as you can
I cannot create a crash here even if I force feed that profile into Qimage.
Hopefully,
Fred
