MacBook battery cable Problem

Hello, I have a 2017 MacBook Pro 13-inch. I recently replaced the screen, and after the repair, the laptop would not power on unless it was connected to a high-wattage charger. It does turn on with the AC adapter, but there is an “X” over the battery icon, and if I unplug the charger, the laptop immediately shuts off.

I suspect the issue may be the battery ribbon cable, which I’ve already ordered, but I wanted to see if anyone else has experienced this or knows what the problem might be.

Thanks in advance!
