it all started when i decided to update the unity from version 2020.1.11 to 2020.1.15
in doing so all the vuforia files disappeared from the project, I tried to download again in all possible ways and the only way I managed was to put the files manually in place
so unity now understand that vuforia is a customized package
but now unity is giving me back this vuforia error
vuforia is in some type of maintenance?or is there any trick i can try?
