I purchased my EOS R back in October of 2018 from a local camera shop. Up until recently, my EOS R had been working perfectly. Recently, I started having an issue where my EOS R will freeze while using the camera. I have had the issue multiple times, and the only way I am able to get the camera to work again is by removing the battery and waiting a few seconds before inserting it again. When the camera is frozen, none of the buttons will work, and the on/off switch will not turn off the camera. The camera has the latest firmware installed (1.2.0). I am also using the lens that came with the camera (24-105 f/4 RF). The lens also has the latest firmware installed (2.0.0). I have tried using multiple batteries (Canon brand) as well as multiple memory cards, with no luck.
