Microsoft To-Do for Mac not opening, crashing immediately

same problem here: forced me to update and stopped working: it got stuck to a fake username (initial showing on the top left:#) and doesn't even open "settings" or "account" when I select them on the drop-down menu (just blinks, but does nothing). Of course I uninstalled and installed a few times, to no avail. From microsoft's account on facebook they replied once, telling me to be patient: an update was coming up. The update did come, I installed it on both laptop (several times, to be sure...) and desktop. The desktop version now works, but the laptop one is still in the same state. I even deleted all the microsoft stuff from the keychain. Nothing... The guys at the facebook messenger stopped replying. I am moving all time-critical stuff to mac's native app reminder. Works fine.
