Description of issue

Hi All,

Apologies for the newbie question. This is my first time posting on this forum.

brew cleanup asks me to report an issue, but I can't tick all the boxes on this page https://github.com/Homebrew/homebrew-core/issues/new?assignees=&labels=bug&projects=&template=bug.yml, so I thought I would start here.

Here's what brew cleanup gives me:

% brew cleanup
Error: undefined method installed?' for nil /usr/local/homebrew/Library/Homebrew/cask/cask_loader.rb:249:in load'
/usr/local/homebrew/Library/Homebrew/cask/cask_loader.rb:557:in load' /usr/local/homebrew/Library/Homebrew/cleanup.rb:178:in stale_cask?'

/usr/local/Homebrew/Library/Homebrew/brew.rb:94:in `

'
Please report this issue:
https://docs.brew.sh/Troubleshooting

When I search for messages about "nil", I see a lot, but nothing exactly similar.

Please would someone advise me how to proceed.

Many thanks in advance.

Simon
