Question What does this unity error message mean?

I was able to troubleshoot the issues I have been having with my current script up until a certain point when I came across this error in unity:

Script updater for Library\Bee\artifacts\1900b0aE.dag\Assembly-CSharp.dll failed to produce updates.txt file

Now, I don't know if this is specifically my code or if it's something else but I wanted to double-check here as it occured after I had corrected several lines of my code. What exactly is the issue that is happening? And more importantly, what is the solution and how do I go about it?

I have provided my code bellow in case it is necessary:

I don't think this is a script compile error. You may want to close Unity, delete the Library folder, and after that re-open the project to see if that fixes it.

 

I built a VR application for android and it worked fine. But when I tried to rebuild it, the build failed and it said this following error. I can't find which component is failing the build. Can I get a solution for this issue? Need fix for this. Thanks in advance!

@Tomas1856 Can you please guide me with a solution! I'm unable to find what is causing the error!

 

Thanks for the help! It helped me build the application. Hope it runs perfectly.
