I have brand new Canon EOS R7 Mirrorless Camera. I run Tamron lenses with a Canon Mount Adapter EF-EOS R
Video works fine but when I take a picture the shutter goes off and it's like it freezes, red light stay on in the back. Camera won't turn off, you have to pop battery out.

What happens if you use a different lens on the camera. Do you have any other Canon brand EF or EF-S lenses to test out to see if the problems still persists. Do you own any RF or RF-S lenses that you could try out too. What is the full name of the Tamron lens that you're trying to use. Also which EF-RF Mount adapter are you using Canon has released 3 of them. The basic one, control ring, or the one filters can be installed in. The link you provided for the mount adapter doesn't work.

Do you have Canon brand EF or EF-S lenses to test out. The Tamron lens is an older lens which maybe incompatible with newer EOS R series cameras. Only Canon can guarantee compatibility with their own EF and EF-S when adapted to EOS R series cameras. It's on the 3rd Party manufacturer to make their lenses work on Canon cameras.
