Crashing with unrecognized selector sent to instance

I’ve had this crash many times when DTPO is in the background:

Application Specific Information:
Crashing on exception: -[__NSCFString isOpaque]: unrecognized selector sent to instance 0x600000135a40

I’ve attached the crash report.

Is there any way I can work around this?

That’s unfortunately a rare & random bug of 10.12.2/3. Do you use any accessibility options, e.g. increased contrast or reduced transparency?

Yes I am using accessibility options including reduced transparency and increased contrast. I’m getting this crash pretty regularly when DT is running in the background.

Disabling the increased contrast or both options should fix this.

Ok. Not really possible. I hope this bug gets fixed as I rely on these accessibility features and can’t reasonably turn them off.

It’s unfortunately up to Apple to fix this.
