Unity exception when trying to build for Hololens

Hello everybody

I'm currently trying to build my app to deploy on Hololens. I've already managed to deploy it a first time, but after some modifications, I cannot anymore. I'm currently using Unity 2018.3.12f1
Any idea how can I fix this ?
Here is the complete error :

Thanks for your help



EDIT :
After removing some assemblies (more precisely MySQL), the build is now working, I should have think about it earlier ahah

Problem solved !
