After Norbert's check I was assuming there was an issue with my machine. I was about doing a clean install (I have a local texmf folder I was about to remove, although no files from there are actually used in the sample). It seems I can omit that now - saved me a lot of work.<br></div></div></blockquote><br></div><div>for what is worth, your MWE errors in the same way on MacOS</div><div><br></div><div><p style="margin: 0px; font-style: normal; font-variant-caps: normal; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Menlo; font-size-adjust: none; font-kerning: auto; font-variant-alternates: normal; font-variant-ligatures: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; font-variant-emoji: normal; font-feature-settings: normal; font-optical-sizing: auto; font-variation-settings: normal; color: rgb(212, 208, 1); background-color: rgba(10, 9, 179, 0.89);"><span style="font-variant-ligatures: no-common-ligatures">(/opt/texlive/2024/texmf-dist/tex/latex/base/ts1cmr.fd)</span></p>
