Many R5 and now R6 owners are experiencing freeze/lockup where the only option is to remove battery. Sometimes it will reboot also after about 20 seconds. It's not lens specific, it is occurring when using RF 70 200mm f2.8 lenses and 300 mm f2.8 mkii, 500f4 mkii , 100-400mm mkii plus a few more. This happens on my R5 once almost every day on a full 6 hour 500 image session with wildlife. Main circuit board replacement is what is being offered by Canon repair centres . You are unlikely to experience it taking a few images for a few minutes , give the R5 a good work out for a couple of hours and it will freeze/lock up. My friend in South Africa explains it here
my camera freezes every day it happened with different batteries different memories. and sd different. the camera started restarting in the middle of my music video work with the musicians in front of me where I only had minutes to do the covers. The worst thing about this is the terrible service from Canon. I bought the camera a month ago and they tell me that they repair it is an injustice. that apart from staying if my work tool touches me to rent and they give me a repaired camera.

Things break, send it to Canon.

A freeze up really sucks, more so for those using the camera for work.

According to the shutter count app, I have 44,000 actuations on the R5 and have never had a lock up.

I use everything from 16-35, 24-70 2.8, 70-200 2.8 ver 3, 100-400 and 300 2.8 and RF 85mm and 24-105. Have not tried the 400 2.8 EF on it yet.

Which shutter count app do you use?

Just an update regarding the lockup issues. I am still on firmware 1.2.0, but have switched from using my CF express card to a 128gb Sandisk SD card (170mb/s). So far I have taken over 4000 frames and not one single lockup! It seems the 512gb Sandisk CF express card wasn’t playing nicely with the camera. I am hoping firmware 1.3.1 resolves this issue once and for all, but am being patient with updating in case any other bugs are discovered... cheers
