Some apps won't open at login first time

Hi,

I recently switched to Opencore and all was well, but a couple of days ago I started to get an odd issue with some apps not opening at login. These are all apps where there is an option within the app preferences to launch at login, rather than ones added in system preferences. Oddly, if I log out and log straight back in, they all open!

I don't know if this is Opencore related or MacOS, but couldn't find any similar problems when searching here or google. Never had the issue in Clover either.

I am on 10.15.5.

Thanks.
