Garage door suddenly bucking in on itself

Yeah Hi, so as of two days ago my garage door has started to buckle in the middle. It looks like the arm is causing it to collapse in on it self as it’s closing. I’ll attach a video for clarity. This has never been an issue I’ve had the door for 10 years and nothing, all of a sudden it’s been doing this.

I do not recognize the brace at the top, but it looks to have failed. The brace or strut lower on the door looks like what I am familiar with. I'm not sure where you are located, this could be some type of hurricane brace we don't have here. It appears that you could possibly locate another strut like the lower one and attach it to the top section to strengthen and also straighten it out.
