Short description of error
When I use lightmap pack in UV editing it either says no mesh object or a error that says

Python: Traceback (most recent call last):
File "C:\Users\cooki\Downloads\blender-3.4.0-windows-x64\blender-3.4.0-windows-x64\3.4\scripts\startup\bl_operators\uvcalc_lightmap.py", line 675, in execute
return unwrap(self, context, **kwargs)

print("\nStarting unwrap")
OSError: [WinError 233] No process is on the other end of the pipe

Exact steps for others to reproduce the error

Hi, thanks for the report. Can you share .blend file in which the error is appearing?

Not sure if it's related but I noticed that Lightmap Pack is also the only operator missing its post operation window (The small window at bottom left of the Viewport where we are able to adjust settings of the last operation)

Hi, Winerror you get is same as mentioned in #99440
Fix for it is still not known to us.
In #99440, rjg has mentioned some tests to perform. See if that solves the issue.
I'll close this report for now.

BTW, does this issue happen in particular file only? What happens in you append that model in new file and execute lightmap pack operation? Still get the same error?
