Urgent Help needed, in TWRP I formatted, now I can’t flash any ROM

I have a Moto X play TX1562 EU version, I accidently formatted (so not just factory reset) in TWRP and now I can’t install anything at all except fo SuperSU and a custom kernel.
Flashing via sideload doesn’t work.

I am at my wit’s end, I can still use TWRP and exchange files via phone and pc with that, but elsewise….

It gives me the error ‘error executing updater binary in zip sdcard <rom name>.zip’
