Bug pasting as Double Duration.
There is a bug when using the paste as double duration feature with the repeat bar symbol.
OS: Windows 10 Version 2009 or later, Arch.: x86_64, MuseScore version (64-bit): 4.1.1-232071203, revision: e4d1ddf

To reproduce the error...
Control-A to select all.
Control-C to copy.
Select the first note or rest in the top staff of the first bar.
Edit | Paste double duration
The bar repeats for the drum part are now empty bars. There is not even a way to add notes to these bars at this point.
The correct score would have double-bar repeat signs.
When saving the score, there is an error "This score has become corrupted and contains errors".
I have attached the before and after scores.
