Looks like a hardware failure of the RTX 3090. The log entries in the 2 regular logfiles indicate a resource issue (1st log) within the driver, which is unusual and points to unexpected hardware behavior within the driver. The 2nd log is more direct (device remove/reset): This is a direct crash or unexpected hardware behavior. Now you changed the computer and just moved the RTX 3090, and the error moved with it. The constant thing is the GPU, so I say this is the culprit.
To make it clear, do it the other way round: use your original computer but a different GPU. The error will probably vanish.
