Unable to update an apk in phone

I have a problem with an application which I had created using ionic 4.1.2. it was created in windows 7.
recently I installed windows 10 and made some changes in the application.
the problem that I have now is when I try to install new apk to update previous version, I see the following message which is good:
" Do you want to install an update to this existing application? Your existing data will not be lost. It does not require any special access"
It is exactly what I want.
But when I press install button, it shows me “App not installed.” message.
I don’t know how to find the issue and how to fix it.

Some one please help me to fix this issue. Thanks
