I have an error in my Kotlin project that I don't understand.
The project was working but then I clone it on another PC and on this other PC I have this error below:

I need to solve this error but I don't know how to do it, If someone ever face this error and/or know how to handle it, I would take the advice !
PS : This is a student project so it is normal if nothing is perfect, normally this was working
