You have to try like this

Delete your build folder in your project root directory
Delete your build folder inside of your project app folder

this both are cache some intermediate files and some debug-gable file so only its happening...

after delete this both folders then rebuild your project it will work properly.

follow this steps

your project root directory looking like that, here delete this highlighted build folder, then go to inside your app folder in this same window

inside app folder have one more build folder its also delete

then rebuild your project.

Here i tried your gradle, here it is:

what you are getting errors is not getting here.

My solution is:

Try to clear your project.
Go to AndroidStudio > File > Invalidate/Restart, it will help.
If nothing works then delete this project create new one.
