I thought the problem from Hyperref phrase with pagebreak also makes footnotes hyperlinked, How do I forbid pagebreaks inside urls without forbidding linebreaks? and Page breaks in hyperlinks seems to be kind of fixed by the solution explained in https://tex.stackexchange.com/a/578405/128042.
But when the page-break is interrupted by a footnote the following code still results in the footnote being falsely linked (both for TeXLive 2021 and TeXLive 2022 in Overleaf):

\insert\footins{\pdfrunninglinkoff}\footnote{AaAaAa}\insert\footins{\pdfrunninglinkon}should work. – Ulrike Fischer Oct 27 '22 at 23:02\footnote{AaAaAa}" with your code "\insert\footins{\pdfrunninglinkoff}\footnote{AaAaAa}\insert\footins{\pdfrunninglinkon}". Thank you this works :) – Jakob Oct 27 '22 at 23:11\thanksis used instead of\footnoteor do you have a fix for that too? – Jakob Oct 27 '22 at 23:38
