Huawei P10+ After Display replacement Rear Camera & Flash not working

Hello friends,
I recently changed the display of Huawei p10 plus. Afterwards I found out flash not working.
Then I checked camera, and once I opened camera, the app crashed and disappeared.
I didnt power off the phone before disconnecting display ribbon.
Is this the reason my camera got short circuit and now not working?
Please help.
After I get some help, I will open the phone again to check out the problem.
Thank you all.
