You really only needed to set the PATH it is not necessary to uninstall an
old tex live (I have texlives 2016 through to 2020 installed for example)

The table of contents code here hasn't changed since latex2e was introduced
in the 1990s so is unaffected by the update.

This is a tex coding issue not one for the texlive distribution so this is
the wrong list, but book class prevents page breaks after the part level
entry to ensure the following chapter and section entries fall on the same
page as their part, but as you only have parts it fails.

If it is just temporary while the document is in draft you could ignore it,
the problem will go once the parts have real content, but if you do have
parts with no containing chapters and sections you could replace

\tableofcontents

by

{\let\nobreak\relax\tableofcontents}

to allow page breaking between the entries.
