[Bug] DllNotFoundException: FirebaseCppApp-12_6_0 assembly:<unknown assembly> type:<unknown type> member:(null)

### Description

I am getting the error in the title in my unity project.

This unity project pulls data from my firestore database on start. From March until maybe mid-May, everything has worked perfectly. Then suddenly, I was getting this error on my editor. This error does not come up on my colleague's machines who are working on the same repo/branch at times.

I have tried reinstalling Unity, deleting library folder and recompiling, deleting firebase modules and reimporting. Same error.

I can temporarily fix the issue by changing the settings on the dll file (FirebaseCppApp-12_6_0) in x86_64 folder. If I turn OFF 'Editor' on 'Include Platforms', somehow it starts working. This is temporary because if I close and open the project then this 'fix' does not continue working.

Colleagues on the exact same branch do not have the issue. I have not touched any firebase setting when it was originally imported. All I have done is write code to access the database and it has worked fine until now.

### Reproducing the issue

May be difficult to reproduce since this has happened suddenly and not on my colleague's machines.

Try:

- Import SDK into new project on same editor (only using Firestore package)
- do:
```
void Start()
{
// Initialize Firestore
db = FirebaseFirestore.DefaultInstance;
}
```
- See if error occurs
