Can't upgrade to v1.14.1

Hi guys,
I have issue upgrading my A150 from v1.13.2 to the last v1.14.1: no update available looking via WiFi on my touchscreen and if I update it manually via USB the WiFi check on touch screen report an update that put back my machine into v1.13.2!

I’ve opened an issue on GitHub but still no response! Any idea?

Please @Melitta_Snapmaker response to this issue!
