\DocumentMetadata{testphase=phase-III}
\documentclass{article}
\usepackage{amsthm} % causes error. Compiles fine if either this line, or the first line, or both, is commented out.
\newtheorem{thrm}{Theorem}
\begin{document}
Hello.
\begin{thrm}
The limit of a sum is the sum of the limits.
\end{thrm}
\end{document}
When trying to compile the above document, I get the following error:
! Package tagpdf Error: there is no open structure on the stack
If I comment out either the \DocumentMetadata{testphase=phase-III} line, or the \usepackage{amsthm} line, or both, then it compiles as expected.
Or if I leave both lines in, but I comment out the \begin{thrm} and \end{thrm} lines, it will also compile.
I am using TeXworks Version 0.69 (MiKTeX 24.4) in Windows 11 Enterprise. I have used the MiKTeX console to update all packages as of today (June 17, 2024). As of right now if I check for updates in the MiKTeX console, it shows "There are currently no updates available." I get the same issue using LuaLaTeX, pdfLaTeX, or XeLaTeX.
