Description of issue

any attempt at update/upgrade or even doctor attempts to update this formula.jws.json file and then fails.

That is the package definition so it's a pretty critical part of brew. What does this command say:

ls -al /Users/mattly/Library/Caches/Homebrew/api/formula.jws.json

[mattly]

the file is missing

there was probably some output where brew update failed, but I've since lost it

[gromgit]

What's the output of:

ls -al ~/Library/Caches/Homebrew ~/Library/Caches/Homebrew/api

?

I'm having the same issue, but with the output of
-rw-r--r-- 1 danalee staff 27592434 Oct 2 23:53 /Users/danalee/Library/Caches/Homebrew/api/formula.jws.json

when I tried your command.

[gromgit]

What's the output of:

ls -ld ~/Library/Caches/Homebrew ~/Library/Caches/Homebrew/api

?

[mattly]

so it turns out some process had surreptitiously installed the intel version of Homebrew on my Apple Silicon mac, and this issue was related to that. I had to remove both installations of Homebrew, remove the ~/Library/Caches/Homebrew directory, and reinstall the Apple Silicon version in order to get it working again.
