Meta Attributes no longer work for seemingly no reason

[TheEmbracedOne]

I noticed that BoxGroups no longer works on my scripts. I thought it was something in that specific script I made, but I couldn't find anything wrong there. I then checked the example scene and it doesnt work there neither. I removed NaughtyAttributes from my project then reimported it, but it doesnt fit the issue. It used to work before on this exact setup with this exact Unity version. I did not touch the NaughtyAttributes scripts.

Version is 2.1.4 My Unity version is 2021.3.9f1

Upon some further investigation, it seems that it affects Meta Attributes as the EnableIf/DisableIf and ShowIf/HideIf also don't work. In case of "ReadOnly", on the sample script, readonly int doesnt work but the rest do (see screenshots below)

Any idea what might be causing this?

I figured out what caused this. It's an asset called NG Missing Script Recovery, that, as soon as I import, will break MetaAttributes.
