Display (MENU) font size in google docs and sheets (not gmail etc.) is tiny

Problem:
My MENU fonts (not the document fonts) - when using Google docs, sheets, slides and forms (but not calendar, drive, mail, photos) displays extremely tiny.
I haven’t found how to remedy this (where ARE the settings for menu size in docs and sheets? Is this brave or Google issue?)

Steps to reproduce:
I have repeated it again in different browsers (brave and chrome only; firefox it’s ok).
see screenshot.

Expected result:
To be able to read


The two files show brave with 100% and 200% zoom on google docs - but the menu stays far too tiny to read.

When does it happen
All the time, since about 2 weeks ago.

OS:
Windows 10. Brave version: 1.62.156
