Describe the bug Drawing a layout fails with the following traceback:

2 extra bytes in post.stringData array
Traceback (most recent call last):

Note: Does not reproduce on any other computer than one Windows 11 machine.

Therefore no DXF file to reproduce this. Seems to be somehow operating system / computer dependent ?

2 extra bytes in post.stringData array- this seems to come from here:
