Can't install apks after updating to Android 10

[EliSadaka]

I can no longer install apps from apk files in Amaze after updating to Android 10. When I try to all I get is a toast message that just says "Error". I've checked and Amaze does have permission to install apps. This is on Amaze 3.3.4.

I don't think Amaze is the only application with this problem. I suspect it is something related to Android. If I download an APK using my web browser and tap on the downloaded file, it asks with what application I would like to open it with and shows a list instead of starting the package installer. However none of the listed options seem to have anything to do with installing a package.

It also doesn't say the app doesn't have permission to install apps, something I expect to see.
