Update: it was in the Global Macro group. I deleted it from there, then recreated the macro in the "All Macros" group. It still doesn't work, unfortunately.
That means the macro is enabled, else ⌃B wouldn't work either.
Have a thorough search for conflicting hotkeys by selecting the "All Macros" Group in the KM Editor window then entering hotkey:v in the search box. That'll show all the macros with V as the hotkey, regardless of modifiers. Eyeball the list to check for conflicts with enabled (not greyed out) macros.
If it worked before but not now -- what's changed? OS update? Other software installation? Have you got something like Better Touch Tool that might be capturing that keystroke before it reaches KM?
What OS version and keyboard layout are you using? That'll help others try to replicate your problem. Does ⌃F work? Have you another keyboard you could test with?

Yep, I checked those; nothing else uses that hotkey:

I tested it on two macbook pros: a current model and a 2021. Both have the same problem. I don't use Better Touch and run very few pieces of software (none of which use this hotkey).

Does ⌃F work?
Yes. For some reason, it's just V that doesn't.
I had exactly the same issue, Alt-V worked for a long time and then suddenly stopped to work. As I am used to this short-cut I now use a macro that works with a named clipboard, in my case named «Clipboard We unformatiert», you have to create your own named clipboard and put that name into the macro enclosed.
That's... weird. That ⌃B worked to trigger the original implies that that it was the ⌃V trigger that was at fault. That the new version works implies that the original macro was running but the "Folder System Clipboard" or "Type ⌘V" actions weren't working.
I've a feeling it was/is the "⌘V" action. Note that if your latest version runs as written you'd be pasting data twice -- once unstyled from the Named Clipboard, then again but styled from the System Clipboard.
