If this helps, the browser console reports this error:

Looks like you've configured an infinite loop in CB Conditional. This can happen if you've a field conditioning itself or conditioning its own tab. This is then causing a fatal JS error and is why input masks, button, etc.. don't work. Please ensure everything installed is completely up to date as CB Conditional has some protections against infinite loops, but you should review your conditions to ensure they make sense.

Your advice really helped, thank you!
I attach a screenshot of the field that I disabled. Three conditions are used here. I can't understand why they worked like that. In all three conditions, the field type is "file".

So everything works fine after disabling that one field or unpublishing CB Conditional? Conditions against file fields shouldn't cause errors. If I am understanding correctly those 3 fields are all file fields, but what is the type of the field the conditions are on?

The type of the field the conditions are on is "Single check-box".
I realized what was going on! The fact is that these fields of the "File" type are located in a tab that is hidden for the registered user. That's probably why there was a conflict. I've fixed it now and it's still working.

How was file fields tab hidden? Attempting to duplicate the issue locally so I can see about fixing this. It's fine if for example that situation doesn't work (although it should as it should just see that the file fields have no value), but we absolutely do not want it breaking your site in the event it doesn't work (which that condition scenario does). If I understand correctly it's the below setup that fails.

Tab 1
Checkbox Field

Tab 2
File Field 1
File Field 2
File Field 3

Checkbox Field is conditioned based off File Fields 1-3, but Tab 2 is hidden.
