You seem to be showing us that you have TWRP installed. I cannot help if I have to second guess what is going on. 
Are you able to get a log from Easy Installer?
Please do not see the following as a remedy to your situation, but can you tell me whether you got to the stage illustrated here and were you able to Wipe Data? Easy Installer stops on Tap on ‘Do not install’ - [Edit, TWRP.apk] - SM-G950F - #6 by aibd
