Just had time to try to evaluate your solution and, if I simply place a 12F683 and no other components, then it no longer crashes using my code (if I comment out the Sleeps) ... but as soon as I try to add more functionality then it all crashes.
Maybe it's a little early in development and it's possible that I'm looking at "beta" type problems that time might resolve ... it's not a show stopper as the last versions(4.15, 4.13) work OK.
By the way, thanks for adding the Logic Analyzer (from my thread a few years back) ... it's such a handy display.
