Just checked, you can open the door. Maybe you have a bug when some triggers won't work, because in one of my playtests i had something similar, but with dialogues. And by the way, when you tried to open the door, did you get a black screen fade or not?
yes even that yellow door doesn't work, now I'll give you 2 videos so you can seehttps://www.mediafire.com/file/2lhq2xzi691hzl3/My_project_2025-10-18_17-49-59.mp...

I figured out the problem. Somehow, in the second video, where you tried to enter the door with the yellow outline, you didn't complete the conversation with the guy (he should give you the newspaper and say goodbye, then leave), and he left without activating the trigger that would allow you to enter the next level. In this case, for now, you can just restart the game (not level) and try again. Only you had this certain problem for now. Basically, you just ending dialogue too fast
