I had this error on overleaf that block the compiler. It seems that I have an error with a hyperlink in the LaTeX code. I try to remove all changes between my older versions, but nothing changed.
It's like if the code doesn't change anything to the error anymore

I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
Runaway argument?

I suspect you've forgotten a `}', causing me to apply this
control sequence to too much text. How can we recover?
My plan is to forget the whole thing and hope for the best.

I was able to resolve the error by temporarily removing all the \usepackage commands and recompiling the document. After doing this, the error no longer appeared. I add again the \usepackage and everything went well!
