Now I have uninstalled and re-installed unity hub, unity editor and all the files and folders.
Now when I installed unity hub and tied to install editor, I got unity new version 2021.3.2f1
I installed that new version and for now I have not faced an error like this.
Any ways if fixed this error in this new version, thank you so much!!
