I understand you already use /e/OS and some installed apps,
I hope your device is running Latest Samsung Firmware that is based on Android 9.0 (Pie),
And got a fonctionnal recovery manager installed.

Donwnload Latest /e/ image (without errors or pause) from here :
.
dev https://images.ecloud.global/dev/dreamlte
.
stable https://images.ecloud.global/stable/dreamlte
.
boot into recovery mode,
and just install the .ZIP file (TWRP),
or Apply update using the .ZIP file (recovery-e),
from internal or external SDcard memory…
as explained here : steps (8) or (9) of this user friendly guide :
BUT WITHOUT FACTORY-RESET OR WIPING OR FORMATING ANYTHING
