Could you before doing this, please update to a Nexus nightly at least? TrueHD has seen many, many fixes since January - and yeah - there was some stuff with the Packer not correct, so please first things first. A nightly is also fine.
Version: Starting Kodi (20.0 (20.0.0) Git:20230115
Edit: Simplest: Backup your .kodi directory and shortly upgrade to kodi's nightly ppa - thx.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

Can you please first try if the issue goes away if you run it at 1920x1080 at 24p? Only?

You could try LibreELEC from a USB stick as a groundtruth comparison. While I don't think it's a bandwidth issue (60p works), it seems that you can influence it with the changed kernel. Problem with such random tip kernel upgrades is: random different stuff might happen, the good or the worse - just like you see it now. It might be worth to open a kernel bug with the intel people and providing them all possible logs with drm.debug=0xe enabled. At the end, it might be small details of the way the HEAD is configured in 24p vs. 60 hz mode. HDMI under the hood might use 12 bpc for the one and something else for the other ... -> maybe your AVR remote's info button already shows a data format change here. Just an example: It might be that in 24p mode the HDMI uses RGB888 or YUV444 with 8 bit while in 60p under the hood a yuv 422 12 bit output happens. Both things the kernel can decide and do like it wants.
Or more simple things like: Audio-Clock 192 khz / 8 channels / 16 bit not stable in 24p mode. From the effects kernel can play multiple roles here.
But try LibreELEC from USB stick first. It uses a newer kernel from a tested environment. Also does not matter if you use the newest LE or something older. Your J4105 for sure worked at a point with 24p.
