There's an obvious kernel splat in the log, but nothing obvious about why that occurred, and Kodi has started in 'off-screen' mode.
Are you using any kind of HDMI adapters or an Argon case?
They are known to cause various HDMI problems, try without the case.
Yes, I'm using an argon case.
Please try again without that case.
I'm using a RPi5 with an Argon case, and wishing I'd looked here before updating.
Argon cases are "the gift that keeps on giving" for support issues

Ah well, at least we know!
But they are very nice cases. Is there anything I can do to help you get this fixed?
I've reverted to 12.0.2 and the picture is back. Happy to update again and grab whatever files you might need, but I'll have to do this via ssh, and may need a little guidance.
If you append video=HDMI-A-1:1920x1080M@60 to boot params in cmdline.txt (to force the initial kernel DRM state to 1080@60) does that solve the issue? - I'm wondering if it's trying to output at 4K (for reasons unknown) and the TV isn't liking that.
I'd also be interested to know what shows on screen if you remove the SD card and let the RPi boot to the test screen. Does it show that an HDMI device (and EDID) are detected?

I'll give that a go, although my TV is 4K.

Even if the TV is 4K the Kodi desktop should be run at 1080p: https://wiki.libreelec.tv/configuration/4k-hdr

Raspberry Pi 5, and it doesn't fix it here. Tried both HDMI ports.
Any information I can give you? I'm going to have to revert it pretty quickly, since this is my 'main' system.
Actually, scratch that.
With that in the file, and the HDMI plugged in closest to the power cable, it does work, as long as the HDMI is plugged in at boot, and not afterwards.

You should be using:
video=HDMI-A-1:1920x1080M@60D
The D means assume it's connected (otherwise you will need to have a display connected at boot).
You should always use the primary hdmi connector (closest to power connector).
