Failed manual install v1.6.0 on Android

I open this issue because I am unable to install the version 1.6.0 on Android manually downloading the .apk published on the releases.
I received the following error:

So I managed to install the .apk file without the default package installer and I got this error:

Collecting some log from the installer I received the same specific error "Failed to collect certificates"

`1770297615.566 1000 1857 3140 I PackageInstallerSession: Session [60126885] was destroyed because of [Failed to collect certificates from /data/app/vmdl60126885.tmp/PackageInstaller: Attempt to get length of null array]`
`1770297615.570 1000 1857 3140 D InstallDependencyHelper: Session complete for 60126885`

Maybe this is related? https://github.com/DefGuard/mobile-client/issues/154#issuecomment-3751707710

I want to specific that with the previous .apk app version v.1.5.1 this error doesn't occur and the app is installed correctly. I'm manually installing the .apk beacuse I'm using a de-googled Android OS.
