Lightroom crashing when using Negative Lab Pro

I’ve had Negative Lab Pro v3.0.2 for quite some time, but have only finally started using it. I’m running Lightroom Classic 14.1.1 on an iMac with Sequoia 15.2, and every time I try to convert a few negs, or do roll analysis, Lightroom keeps crashing. I’m having to do all the conversions one at a time. Can anyone help? Thanks!
