menu bar font too small. How to change

Running version 6.0.4.2 and the main menu bar ( File, Edit, … ) on both writer and calc are way too small. How can I increase the font size.

You probably can’t. See https://bugs.documentfoundation.org/show_bug.cgi?id=101646

I’ve not found an option inside of LO, but for Windows 11 I have adjusted the display properties (System - Display in Settings) to change the Scale to 125%. This is a system-wide change that makes all menu fonts seem bigger. For me, the extra 25% makes LO menus legible enough to use. (This should work on Windows 10, too).
