Canon 7D MKII exposure problems

My Canon 7D MKII is 4 years old - last year due to a firmware update it needed servicing. I have found that the exposure has been going wrong. This could be user error - but I have never had this before - any ideas.
It could be user error of course - but I have been using it without any problems for 4 years.

The problem seems to be lines coming under flash or strong light see below

Wow, that's crazy!
are these images straight out of camera?

Any chance it's a corrupt card? (although, this does not look anything like how that usually manifest,. )

Certainly looks like another trip to Canon and likely a new camera is in store.


EDIT: Wait, tamron lens, any chance you have some form of digital lens optimization turned on in the 7D2?

Those are almost straight out of camera I just cropped one and converted to jpeg.

It was with two separate lens, most photos are fine (see below) and if I use an external flash it is fine.
