unable to open an mscz file which includes repeat signs

I cannot open mscz files where I included repeat signs (left, right and left_right).
After inclusion of the signs, the signs are correctly played by musescore with the option "play repeats".
I can save the file but , afterwrds, Musescore (version 3) crashes when attempting to open such files.

I tried to export such files to mscx files but Musecore crashes again.

Is it possible to save and open mscz files with repeat signs?

Thanks in advance
Eduardo
