Question Can't open project unless I delete library folder

Hello devs, as I said in the title, I'm running out of time with this delivery and I can't figure how to deal with this bug/issue. It wastes a lot of my time because it's a medium project.

I don't have a lot of info but this is the situation:

Unity Info:

• Unity Editor Version: 2019.3.6f1 (5c3fb0a11183)
• Using HDRP 7.1.8.
• This is the manifest of the packages, just in case it could help:

Code (JavaScript):

49.     }
50.   }
51. }
52.  

In short:
1) I can't open this project unless I delete the library folder.
2) This only happens with this project, I can open other projects without any problem.
3) After resolving packages it hangs.
4) I have to delete the library folder, then open unity, Unity has to rebuild the library folder, this process took between 1-2 hours.




Once it finally opens throws the next error:
Please I need to solve this as soon as possible,
Thank you all for reading this.
