Copy-paste multimeasure rests containing a full measure, or not after cuting, causes corruption/crash
This is an extracted part from a file that has corrupted measures which are hidden with a multimeasure rest. By attempting to fix the corruption, i.e. by entering rests in the corrupted measures, Musescore will crash. This crashes Musescore 2.03 under Windows and all the Windows nightly builds of 3.0.
The corruption starts at measure 200 in the attached file.
