Apk not installing on 3.0

[Nes]

I have S10 lite and after updating to 3.0 unable to install apk. Is there a solution?

Thanks I have already tried to reset all the preferences and it is happening with all the apps

Sorry if none of that worked for you.

You have 2 options now, First factory reset.
2nd. Visiting service center.

One thing you can try is that go to settings, apps, then click on the three dots on the top right corner and click "Show system apps" and then go to package installer and clear cache and data aftwr clicking on storage.

Then please visit service center and reflash the firmware of your device. Don't forget to take a backup becauee your data will be lost.

Thank you for all your support, the issue is resolved by factory resetting the device. I tried various videos and researched on article and forums, nothing helped. Resetting the phone helped
If someone face this issue please reset your phone and it should be fixed

I'm facing the same  issue exactly

is there any hope to fix this without doing " factory reset"

Try clearing cache and data of package installer under system apps.
