EOS 7D Shutter stuck closed

Hi guys

I have been a nature photographer for about 5 years and I have been using my Canon Eos 7D for about 2 to 3 year's and for some reason while I was photographing birds it suddenly just showed a Error 20 on the screen and then the shutter didn't want to open anymore.I have switched the camera off and on, taken out the battery, update the firmware , factory reset it, and even just left a bit too see if it will sort itself out but nothing happens just shows the same error. For some reason when I click on menu and go to Dust Delete Data and press ok then it opens the shutter but not when I just press on the shutter button. I am not sure if there's a problem with the mirror not opening all the way or something else to do with shutter, but the mirror seems fine to me.

Hope someone can help me understand what is wrong so I can get back to photographing again. Thanks in advance
