Kernel Panic, even from clean installation via internet recovery.

IIRC the "EmbeddedOS" is the name/reference to the OS that is uploaded to the Touchbar to make it functional. More than likely this will be a hardware issue, but it is hard to say whether third party software could be interfering. If a clean install has the issue and you don't restore from a backup or install any third party software, then you have confirmed a hardware issue which will need to be repaired.

Personally I would not repair any 2016-2020 Intel Macs as I feel the money spent on repairs would be better spent on a new laptop.

It appears you have a MBPro 15" (2017) model if I interpreted the 14,3 designation in the Kernel Panic log correctly.
