Feedback Rebuilding the Library takes forever on a single thread

I am developing on a large project. Something went wrong and the editor started to rebuild its library (pc platform). It is currently still processing. I noticed that it now spent more than 2 hours (still going) processing .shadergraph assets. (The progress bar was at 99.999% 2 hours ago... still at the same place now). The windows task manager indicates that this super long and tedious process is done on a single thread, out of 20 available on my i9. This is only an example but I often notice that many unity processes are single threaded. Please try to jobbify as much as possible... it would be greatly appreciated. Thank you!

 

After 2 hours 36 minutes, i killed unity. I am almost 100% sure that I kept seeing the same shadergraph asset being processed over and over again, in some sort of infinite loop. I reopened the project, waited like 2 minutes and hop, it was ready to use. Definitely a bug!
