I posted this reply on another thread. I had the same issue and also a very powerful PC (with 24 CPU cores and also a nvidia RTX 4060 and also a fast SSD. while it’s checking for updates sometimes it takes about 10-15 minutes on my configuration, which means if you’re lower than this it can take probably longer. Many times I thought it was stuck and tried to cancel out and it only makes the problem worse and it would take longer in the future. As there are many things need to be checked based on what is installed , this happens. clearing the cache may help, but i heard in some cases you end up messing up and reinstalling everything. So if you have a powerful pc give it 10-20 mins and it finishes. Or if less powerful CPU/IO then 30 minutes or so.
