When building artifacts: package R does not exist, broken library classpaths to res folder

I have been stuck on this bug for a few days. I have an android project with three modules. I need to build a .jar artifact to update my AWS lambda connections, but suddenly this past week whenever I click Build->Build artifacts..., the build fails with dozens of package R does not exist errors. When I do a regular build or run the app on my emulator, these errors do not pop up. Why???
I have tried many things and scoured the internet. No progress. I have also noticed that in the project structure, several of the libraries have broken classpaths that end in /res . Is there something going wrong with my resources file?

Here is my error log from the Build artifacts... build:

Does it work via Gradle?

What Android platform version is used?

Does what work via Gradle? Creating the .jar file? I am not sure how to do that.

I'm not sure what your second question means either. Here is a picture of part of the project structure that shows some Android platform numbers.

Run this in the command line from the project root directory:

gradlew build

Oh, ok. Yes, the build is successful with gradle.

So if you delegate build/run action to Gradle everything will work too? https://i.imgur.com/AmWjMZR.png.

Yes, when delegated to Gradle everything worked. The issue is only with Build > Build Artifacts....

I'm sorry I ghosted here for a week. I ended up updating my IDE to version 2020.2 and updating all of the plugins and now Build > Build Artifacts... is working with no errors. So I'm still not sure what the issue is, but apparently it was a bug that was fixed with the update.
