FieldAccessException: Field `Unity.Netcode.NetworkBehaviour:NetworkVariableFields' is inaccessible from method `Unity.Netcode.NetworkBehaviourUpdater:NetworkBehaviourUpdate ()'

Description

i upgrade netcode 1.2 to 1.5.1, and i import the whole package into my project(because i need use addressable for networkprefab, so i
modify some code on generating networkobject hash id method), the server works fine on the editor mode. but i got an error when working on dedicated server(win64) build, this error message shows every frame.

I got this just now after doing a bunch of size and performance optimisations, I think it might be the compression mode, I'll fill u in once I've figured the culprit

[gradientogames]

I have found the culprit. The whenever the stripping level is not disabled, it causes the issue, I'm assuming its because the build is stripping the networking code even though it is required.

@gradientogames
Yeah, there seems to be some issues with the ILPP side when stripping is enabled. We do have a fix for that issue, but for the time being if you prefer to use only the current released package then you will need to have stripping disabled (until the update/patch is available).

Otherwise, if you are more adventurous then you could replace your com.unity.netcode.gameobjects entry in your manifest file with this:
"com.unity.netcode.gameobjects": "https://github.com/Unity-Technologies/com.unity.netcode.gameobjects.git?path=com.unity.netcode.gameobjects#fix/ilpp-stripping-and-coreclr-compatibility",

And see if those fixes resolve the issue you are running into when making a dedicated server build.

@gradientogames
Just wondering if that branch resolved your issue?
If so, PR-2614 is being reviewed and those fixes will be in the next update.

If not, then let me know so I can investigate the issue further.

[gradientogames]

It worked!
