GPDWIN 2 Touchscreen stopped working

Hi all, just got me Gpd win2 touchscreen gone. I was working fine until CCleaner installed a 2020 version of goodix touch screen driver. The screen started to have tge 10 touch points popping at the same time (ghost touch). So i decided to go for a clean install. Since then,the touchscreen never responded again. Tried clean install with official site os firmware. Tried installing drivers, v2, v5, auto installation, manual install, nothing works. The divers are there. It is shown as 10 points touchscreen in windows properties. But nothing is working. I was thinking maybe removing the battery and the touchscreen cable, assemble it again and test as last resort. Waiting for a reply to this. Ill be happy to try anything.
Many thanks.
