Why is my loopback interface losing its address sporadically?

After I upgraded to Fedora Linux 36 from 34 (first to 35) I'm getting an issue I had not faced before. The
lo
interface is losing its inet address and that's causing issues with programs that make heavy use of internal networking like IntelliJ Idea. This is what it looks like right now
lo: flags=73 mtu 65536
loop txqueuelen 1000 (Local Loopback)
RX packets 945854 bytes 68873995 (65.6 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 945854 bytes 68873995 (65.6 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
If I run sudo ifconfig lo down && sudo ifconfig lo up
then lo
gets its address back but if I hibernate the laptop it loses the address again and programs start to crash and not work correctly. Also, after restarting the interface I need to restart the docker
service too otherwise I can't access the containers normally. Anyways, I'm not sure why this started happening but I want to fix it, any ideas why it might be happening? Please let me know if you need me to provide more details.
