My Canon R5 has been having issues copying video files from the camera to my computer via USB-C.
I recorded ten short clips and played them back successfully on my TV through the HDMI port.
Next, I moved the camera body to my desktop computer, connected them through the USB-C port and copied files from the camera's SDXC card to my computer's hard drive.
Copy completed and four thumbnails appeared on my computer screen showing thumbnails with positive GB file sizes and recorded time stamps.
The remaining six files indicate 'zero bytes' file size, thumbnails with no content.
I retested playback of all these files on the back of the camera and all ten played back fine on the rear LCD.
The data is there in camera on the SDXC, but the camera won't send data from those last six video files to my computer.
I'm not having issues copying still photos, just video.
I have repeated this test with the same results.

20210204 Problem Solved.
Canon's OS Utility App 3.13.10 for Windows is the key.
I recorded 26 short video files late on 20210203_pm.
All of them sucessfully tranferred from R5 Camera body directly to my Windows computer through USB-C and played back OK.
Case closed for now.
Yes, please refer to the fine print in the jpg screen grab within the post:
Six of ten files show zero data when connecting Canon R5 directly to computer via USB-C cable.
These same ten files read positive data values when the SDXC card is inserted directly into the computer's card reader.
All ten files play just fine when SDXC card is inserted into computer's card reader.
Transferring files using EOS Utility from R5 through USB-C show improvement, but one remaining file failed to transfer: CA9A7000. (see next jpg) even though meta data says 01'23" length of clip.
This next DPP4 screen shows nine clips downloaded total utilizing Canon's OS Utility 3.13.10 .
The first five playback fine.
Four clips have a right hand turn arrow.
Three of these four playback OK, except the last file CA9A7000 does not play back at all.
What do the right hand turn signal arrows mean?
