The key combination "Command + Shift + \" can't be used because it's already used
After several problems arose in the last few weeks on my Mac, I decided on a clean install of macOS Monterey today.
After reinstalling 1Password and logging into my account, I can't set anymore the 'Show 1Password' and 'Fill Login or Show 1Password' to ⇧⌘\ and ⌘\ respectively.
1. I can set to other key combinations.
2. None of these combinations are used in any of the keyboard shortcuts in System Preferences.
3. Searching the web, I found this topic where the culprit is Alfred, which I do use. I've gone through every Alfred setting but I can't find anything. Quitting Alfred doesn't "release" the shortcut also. Both apps (1P & Alfred) had their settings restored from the previous install, so they have the same keyboard shortcuts they had working fine before.
4. Quitting every app I have installed doesn't work also. Setting the same keyboard shortcuts in other apps is allowed and work fine.
Any tips on how can I find what's going on in 1Password? :(
Thanks in advance.
