GUI login fails for new installation

No one can’t possible know or deduct what setting in your reused home folder in causing this - suffice to say that we have narrowed it down to your home folder.

I really don’t know - instead of using more time on it - just transfer the file from the non working user to the working user and be done with it.

I cannot be of further help and have no further to add.

You best bet would be to copy things 1-by-1 and narrow it down that way. But there’s no real other, or easier way to do it.
