Invalid Binary Error with reason ITMS-90111: Invalid Toolchain

Hi,
Our app is not able to pass thru Public Release Review this week with the reason Invalid Binary. It failed twice even if it is submitted using Xcode 11.6.
Weird thing is binary validation passes during upload & even beta review however on final review it gives this error.
Anyone can help with valid and working solution for this.
Thanks
