Welcome @Ziad_ishere!
What you see is not an issue with Julia itself. It is caused by certain (upstream) packages in your environment having newer versions whose compatibility with other (downstream) packages has not been ensured yet.
For instance, Functors.jl released a breaking version v0.5.0 last week. Packages which depend on Functors.jl must specify which versions of Functors.jl they can work with, and when a breaking version arrives, it must be added to the compatibility specification. This process is partially automated but still requires manual approval at best and manual adaptation at worst. So it is normal for it to take a few days (or weeks, depending on how breaking the update is).
If you want more detailed information on which packages are blocking the update, you can try to force the version of Functors.jl and see what happens:
pkg> add Functors@0.5
