Harmony 17 wont open some files

Since the quarantine began, I have been using the same Mac from the studio but now at home, I am supervising the animation of several colleagues but I find myself with the problem that when opening scene done on versions 16 or 17 my harmony 17 gets stuck trying to open them and it just doesn’t succeed, when I switch to PC and try to reopen those same scenes I can do it without any problem, what is happening on the Mac version?

Processor 3.4 GHz Intel Core i5
