Bronica SQ-A mirror stuck in up position

Please delete if not acceptable to post this. My daughter returned the camera, I was going through the camera trying to remember the steps. Now the mirror is locked in the up position,  which prevents the charging handle from turning to charge the lens shutter. Lens can only be removed when shutter is cocked.  would love to here and suggestions or ideas.

Thanks hope you have a great week and use some film this weekend, our weather getting great:^)
