I've had my 800D about 5 months now and it's always worked perfectly. Was shooting outside in the cold last week and when i went inside the screen onviosuly fogged up. Let the temp equilibrate for a bit, but here a week later and the camera still can't focus at all. Any ideas?! I'm a vlogger so having my camera out of action is becoming a problem hahah

First reset the camera. Under the Tools menu tab clear all settings. Always do this first when things don't do as you expected.
"i went inside the screen onviosuly fogged up."
What screen? The back LCD? Did you get the T7i wet? Even a little wet? Did you leave it outside where it got very cold and then brought it inside a warm room and tried to use it? If it got wet don't hope for much.
