After I upgraded Ubuntu from 23.10 to 24.04, its boot time slowed down. Every time I turn on my computer, I have to wait 2-3 minutes. I think it is too slow. I have a dual boot(ubuntu and Windows) installed. I tried many methods, but none of them worked. How to solve this slowing down problem of boot? The "Timed out waiting for udev queue being empty" error sometimes raises.

I would be happy, if any one of you fixed this issue. If You need any system info, feel free to ask.
I tried to disable the above services that slowed down my system. But not worked
