: There is no public "one-click" decryption tool for heavily encrypted CSP mods. The keys are hardcoded into the runtime plugins.
For bulk decryption or deeper extraction, QuickBMS (a versatile file extraction tool) combined with a specific Assetto Corsa script is highly effective. This method completely separates the texture files from the core 3D model data. Prerequisites

“Is there perhaps a tool/program or script which can somehow intercept the unencrypted KN5 externally outside of the game or the encryption key, or is it even possible to directly edit the KN5 in some way? Or maybe it’s also possible to reverse engineer the KN5enc to turn it into a decrypter?”

A KN5 file is the primary 3D object format for Assetto Corsa, containing the required to render cars and tracks in the game engine. : There is no public "one-click" decryption tool

Once you have successfully decrypted a file, you need to verify that its structure is intact before trying to load it back into Assetto Corsa.
Ensure that when you export models via Content Manager, you have already clicked "Unpack Textures" into the same directory. 3D models look for texture files relative to their folder path.

For deeper asset extraction, standalone command-line tools offer direct extraction capabilities.
“Hello everyone, I wanted to ask if there is any kind of program or script to decrypt the kn5 files in Assetto Corsa? I tried a thousand different ways, but none of them worked. Thanks.”
