Based on the two pics shows, seems causing by the loosen screw that holding the bolt head.
How many rounds you put through it on that game day? When was your last service it? You know gbb needs to be maintained, especially for those screwed parts after heavily shootimg, need to thead lock them.

Everything cycled just fine, but no rounds came out. After further inspection, my bolt head has broken in half.
Has anyone else had this happen before? I'm baffled how this could even happen because I believe the impact of the bolt carrier is on the rear end of the charging handle? Anyway, I wanted to flag this for you guys as something to watch out for and see what upgrade parts would be recommended to replace the bolt head - Looks like there are the TSC and Azimuth brand steel replacements. Azimuth looks to be higher quality - can anyone confirm?
