"Unknown Sources" files seem to have disappeared from Quest

I built a few projects in Unity a few months back, installed on my Quest, was able to use them just fine after I enabled developer mode. It seems that developer mode is still  enabled (I have a developer tab, the option to turn it on isnt' in settings, I get an option to view a Developer Feed instead of regular feed etc.). But, there is no longer an Unknown Sources submenu in the Apps menu. When I go into Storage, I don't see them under Apps either. I definitely haven't uninstalled anything or deleted anything from my Quest. I have purchased new apps over the past few weeks but there is plenty of storage space left. I know there's been some updates. Only settings I've changed recently was to enable handtracking and voice. Did Oculus nonconcensually delete my files?
