L'app appena creata non funziona su huawei P smart +

Good morning
I tried to produce some small apps that launch my programs that are on the web
Until now I had a lenovo A816 smartphone and everything seemed to work perfectly.
I changed smartphone with a huawai p smart + with android 9 supported with EMUI 9.1.0 and, as if by magic, the small apps stopped working. The ice system that has detected an error.
Do you have an explanation on this?
Thank you
