I hate those windows. If you have a friend with a 3D printer I recommend hounding them to print you a new one. In the meantime to close it a vice grip is probably your best bet, careful though, you don’t want to strip those splines.
I had this same problem. There’s supposed to be a metal faceplate that covers the holes made in the trim so you can access the screws by “popping off” the faceplate. And good luck finding the replacement part. I had to identify the company that made them, find the parent company that purchased them, then go to their parts warehouse to request an investigation for the inventory and wait 3 months to receive it. All because standard replacements were dramatically different
Pop the arm off the window, close the mechanism. Push the window open and closed, lock it closed. If it doesn’t have a lock, put a hook and eye lock on it.

I gave up on “home improvement” years ago. I’m in full “home staving off collapse” mode.

This may go in the "whelp this window is just staying closed" category.
