Extracted the mszx from the mscz, searched for Measure len="-, removed the - sign, moved back into the mscz
It still reports corruptions, but now at least opens. For the remaining corruptions see How to fix a score that contains corruptions.
Start with removing all the parts, regenerated them once all corruptions are fixed
The interesting part is: how did you manage to get the score into this state?

The issue is not related to the Repair Assistent plugin.
