I had a wipe of the dalvik and data cache system before installing the rom. after I installed the gapps pico for arm 64. I did wipe cache and dalvik I restarted and made the root with magisk 16.00. as I told you the tablet overheated and had an excessive drainage of battery. so I made a reactor to the previous rom] [Kernel] [SM-T819] Stock Touchwiz Nougat deodexed and debloated. I do not know what happened.
Hmm strange that is quit simular to the version numbers I'm running.
Have you tried going back to a full stock Samsung rom, a recent one, should read a bit better that is quit recent, and wipe the whole device so it's as fresh as possible?
And start full fresh from there, that is what I would try first,
Latest added pda version is T819XXU2BRB2 in the updater script that works for installing.
T819XXU2BRE1 are the newest Samsung Roms available but haven't been added to the updater script of the current build that is downloadable lineage-15.1-20180616_011608-UNOFFICIAL-gts210velte
