Starting with python 3.12, profiling now stays enabled over threads yet you can't extract the profile data in the threads themselves, which makes it difficult to use for our use case. Our main loop starts the idle loop which starts the parsing threads and this means we can't profile in the main loop and the parsing threads or the idle loop at the same time due to this. Add options to the commandline so you can specify which piece of bitbake you want to enable profiling for. This allows some profiling with python 3.12 onwards rather than crashing.
