I just installed pop os and was upgrading it and it gave me a warning saying "Cryptsetup: WARNING: Resume target cryptswap uses a key file Pop OS" so should I be concerned about it ??

According to this Reddit post you shouldn't be concerned

So Pop OS uses fulldisk encryption, when you unlock the boot loader you also need to unlock the filesystem itself. Usually this means you'd need to type that same password.... again.

Pop OS gets around this by telling cryptswap to pass the password you typed into systemd-boot to the luks encryted filesystem
