Unable to install .wgt app from Usb/web link to Samsung TV(QM32C)

I have developed a web application using Tizen Studio.I can use tizen studio to debug remotely on tv, and the debugging is normal. I also created a tizen certificate and added a UUID, but when I packed it up and used usb to install it on the TV the prompt “Unable to find the installation file.”
I remember that I could still use a USB for installation last year, but suddenly it didn’t work this year. I don’t know what the reason is. Is there any expert who can help me check?
Tools using: Tizen Studio 6.0
There is a message when packing:The project is a 2.3 version based application, so that the project may not be working on a 8.0 plat form normally.
