Can't use any unity projects due to error message

This is a fresh project with a reinstalled unity and creator compaion. Yet I get this.

  1. Error: Could not load signature of VRC.Dynamics.MathUtil:DistancePointToPlane due to: Could not load file or assembly ‘Unity.Mathematics, Version=, Culture=neutral, PublicKeyToken=null’ or one of its dependencies. assembly:Unity.Mathematics, Version=, Culture=neutral, PublicKeyToken=null type: member:(null) signature:

Try installing the Mathematics package manually.

Window → Package Manager

Give it a few seconds to load the packages, then find “Mathematics”, select it, and click Install.

I can’t remove it because the vrchat sdk is a dependency of it.

Is it already showing as installed or something? I need clearer information here.

Can you post a screenshot of the package manager?

I didn’t find a good dependency checker so I looked at the json files manually to see how/why mathematics is involved.

{PROJECT}\Packages\packages-lock.json mentions burst, so the SDK itself is asking for burst
[email protected]/package.json asks for com.unity.mathematics 1.2.1
[email protected] is what I have in {PROJECT}\Library\PackageCache

What version of com.unity.mathematics is in the Library\PackageCache?

Or maybe see what the package resolver says

I can’t acesss that as the vrchat SDK only show reload SDK

Its more that I have to remove the base sdk first which causes issues with the cretator companion

Alright, so what about the library package cache?
