I ran brew upgrade on my Mac yesterday, and it upgraded PHP from 7.4 to 8.2. Then I found that the version of deployer we're using is not compatible with this, so I wanted to revert to 7.4.
I tried
brew unlink php
php link --overwrite php@7.4
Now when I try to use PHP I get a fatal error:
dyld[18837]: Library not loaded: /usr/local/opt/icu4c/lib/libicuio.71.dylib

Abort trap: 6
How do I fix this?
I tried brew upgrade icu4c and it said
Warning: icu4c 73.2 already installed
and didn't do anything.
I tried brew reinstall icu4c and it said

Neither of these solved the php error.
I have a Time Machine backup, but so much stuff was upgraded yesterday that I have no idea what I need to restore.
