I’ve been successfully running Lightburn on a 13" M1 MacBook Pro. I just upgraded to a 14" MBP running Monterey, and Lightburn immediately crashes on launch. I’d copied over my old machine via Migration Assistant, and when Lighburn wouldn’t launch, I grabbed a fresh copy of 18.104.22.168, which does the same thing.
The crash report reads (in part) -
Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000001, 0x00007ff7ffc73af0
Exception Note: EXC_CORPSE_NOTIFY
Termination Reason: SIGNAL 5 Trace/BPT trap: 5
Terminating Process: exc handler 
Triggered by Thread: 0
Application Specific Information:
assertion failed [header->version <= kProjectSourceVersion]: runtime library is newer than runtime
Any ideas on how to get this going? Thanks!
