Thanks to everyone here, after both installing the old windows app and removing updates from android then install from galaxy store, I can unlock from my computer again.
The only issue left for me is that the PC dialog window remains black when I enter my PIN, so basically have to blind type my password, better than before for sure. I am wondering if anyone else is also having this symptom even after the downgrade. My phone is Z fold3 so it might contribute to this issue?
