Hello,
I saw old communication about this topic and that last was from 2019: "the row height can not be changed directly, but you can trick it by changing the font size (to a certain degree) in a column you aren't really using (and then hide it)".
I created an additional column, choose a row increased the font size in the new column cell, then hid it. But when hidden the row height went back to its original size.
Thanks!
Column created and font increased to 32 shows a wide cell height:
Column is hidden (although on font 32) back to narrow:
