I have tried everything from the instructions in the error log and several other available solutions of StackOverflow but still not able to solve and getting the same error.

Answer 1

The solution to your problem is to remove the whitespaces in your username. In fact, the whitespaces anywhere in your path.
In your case, your username is Mr Rushil Dewasker. That's two whitespaces.
Change it to something without spaces and rebuild your project. It should work fine after that.
I had this problem once, myself.

Answer 2

Well the error itself shows some way to solve this issue. Have you tried that?
