Damn it! I can not find any solution to fix this bug.
If you dont know what i mean: Recoil is reversed and goes down instead of up.
To me, this bug or problem is occurring on the following weapon packs:

- Counter-Strike Weapon Pack
- Counter-Strike: Source Weapon Pack
- Half-Life SD Weapon Pack
- Half-Life Weapon Pack
- Half-Life: Opposing Force Weapon Pack
- Half-Life: Blue Shift Weapon Pack

All created by the same author "Полковник" of course.
And yeah this problem is not present for everyone just a few...
Of course the first thing that comes to mind is that this has to do with a conflicting Addon.
But its not! I disabled every Addon i have and also tried to only enable one weapon pack at a time.
The problem was still there so its not a conflicting addon.
However, i have 4 more weapon packs that do NOT have this recoil problem:

- Counter-Strike: Global Offensive Weapon Pack
- Left 4 Dead 2 Reworked Weapon Pack
- Call of Duty 4 Modern Warfare Weapon Pack
- Black Mesa Weapon Pack

Obviously also created by "Полковник".
Why are these packs working while the others dont?
I didnt play gmod for quite some time and the other day, a new update came out that
added Half-Life Source Entities.
I never used and/or subscribed to any of these Weapon packs before the update so maybe this is the cause?
The problem however is that other people wrote comments under these Addons referring to
the same problem with the recoil and these comments are from 2018.
Which means that this problem existed before.

Another thing that isnt the same for everyone, are the games they own and have mounted to gmod.
I unmounted all games and tried again only with the "Half-Life Weapon Pack" enabled.
Bug was still present. So what the hell is causing the recoil to be reveresd?!
Normaly i wouldnt care and just search for another addon but these Weapon Packs
are the best i have seen so far! Every weapon feels, sounds, acts and looks exactly like they should!

So does anyone know a solution to this or have any ideas regarding this problem?
