I apologize for the inconvenience.
I don't know the cause, but did you save the scene with the scene rotated 90 degrees?
In that case, to maintain compatibility, the rotation is automatically restored before saving.
It looks like there is an error in that part. I'll try to investigate the cause.
Thank you for your report.
