Debloater Preventing Phone from OTA Update

Hello all, I'm having a slight problem, I noticed that AT&T keeps trying to roll-out a new software update, however, my Galaxy S6 Active will download it fine, and then when trying to install the update I get prompted with the message "The install cannot be completed".

I thought at first this must be due to an application that I had disabled, but unfortunately it was not the case as I enabled every blocked app, and yet I still got the same error.

8 files still remain disabled even though I tell Debloater to "unblock" all and they include the following (I have tried countless times to enable these files with no luck):

ContainerAgent2.apk
EmergencyLauncher.apk
KnoxBBCProvider.apk
KnoxKeyguard.apk
KnoxShortcuts.apk
KnoxSwitcher.apk
KnoxTrustAgent.apk
KnoxVerifier.apk

I even performed a hard factory data reset, and these apps still remained blocked. I just want to be able to receive OTA software updates. Any ideas on what I can do? Thanks.
