Recently in my installation of VS2022 the tooltip message font size went microscopic as shown in the clip below.
I've gone thru the font size options in the menus but haven't been able to find anything that will change the size.
Any ideas how to get that back to a readable size?
Go to Tools → Options → Environment → Fonts and Colors and change the drop down to "Editor Tooltip" and then change the "Size" drop down value (the default is 9, yours appears to be set to something like 6):
