Crash on wake/unlock with external display connected (EXC_BREAKPOINT on wallpaper.refresh.queue)

LookAway intermittently quits without any visible error when the Mac wakes from sleep with an external display connected.I initially suspected that connecting/disconnecting the external display was the trigger. However, I have now reproduced the crash while the external display remained physically connected throughout the entire sleep/wake cycle.I have collected four independent .ips crash reports, and all four crashes have the same characteristics:LookAway 2.4.3 (548), App StoremacOS 26.5.2 (25F84)EXC_BREAKPOINT (SIGTRAP)The faulting thread is consistently on the serial dispatch queue:wallpaper.refresh.queueThe top frames are inside the LookAway binary, followed by libdispatchThis appears to be related to display reconfiguration and possibly wallpaper/lock-screen refresh handling.Most recent reproductionHardware setup:MacBook ProExternal Dell U2725QE displayTwo-display setupSteps:Start LookAway normally with the external display already connected.Put the Mac to sleep.Leave the external display physically connected.Wake the Mac and unlock it.LookAway silently quits shortly after wake/unlock.The external display was not plugged in or unplugged during this reproduction.I can provide all four .ips reports and the debug log.
