I am new to learning Android Studio. I installed the IDE and every time I create a new project, I get an error. I tried changing the Gradle version, but it didn’t work. I searched in several places and couldn’t find a way to solve it. I want to fix it so I can learn, but I feel stuck and don’t have acquaintances who program Android to help me. Here are the errors that appear:

Im trying to use 3 menus and for that 3 drawer layouts, but only the one in the activity_main is working. do i need to have every drawer in the activity_main or im doing something wrong?

I have a project that has several modules.
In the last few days I decided to update the project, after updating gradlew, libs, I discovered that my test commands stopped working.
