R5 Freezing and locking up while recording firmware 1.8.1

[Nana7_7]

Hello

Lately, I have been experiencing random freezing specifically while I have been recording (I tried all resolutions and frame rates etc...). It happens at random and sometimes it doesn't happen at all. When it does freeze I lose the footage or it becomes corrupted data. I have tried different lenses, changed the battery, downgraded the firmware, reset the camera, and replaced the SD cards but it still freezes.

I'm living in Japan so the language barrier is not helping with solving this problem.I phoned support and they asked me to send it in to check but it's going to take two months just to identify the problem which will affect me negatively. So I'm trying to avoid that suggestion for now.

I looked at many threads about this topic and none of the suggestions/solutions worked for me.

If someone can provide me with a solution that I can try. It would be greatly appreciated.

Equipment:

• Canon original battery
• RF 50mm F1.8 STM
• Sony tough CFexpress: Write Speed: 1480 MB/s, Read Speed: 1700 MB/s
• SanDisk Extreme PRO : UHS-I V30, Read Up to 200 MB/s

This chart might help you.

The store clerk told me to use CFexpress cards but I going to try your recommended choice. Thanks for the chart.

The store clerk was correct.  I think there was an implied recommendation not to use the V30 USB cards for 4K video.  Only use the CF Express card.

Yeah, He said it in Japanese so it's basically a guessing game of what he's trying to express.

He really wants me to send it in for repairs but the headache of trying to explain the problem to them is not worth it. That will be the last resort solving this problem.

Hi, did you find out which of the settings caused the camera to freeze? (I’m having the same issue)
