I don't have a solution for my A42-5G either, and my problem is more complicated and annoying. After years of building my phone to the layout that it had, I accidentally cleared my home launcher app data and figured I could retrieve that from the cloud.
Not only am I experiencing your problem, but my phone is now glitchy, immediately closes apps and notifications randomly when i touch to open them, sometimes opens the keyboard when I click something to type, will close the keyboard randomly as i type, is much slower than before, even freezing up for the first times ever in the 3 years I've had it. The apps that were reinstalled from the backup are all basically 3rd party apps now, even though they were downloaded originally from Google Play store. In their settings they say the source is Samsung cloud backup instead of Google Play store and I cannot look at the app info like you normally could. They are also installed permanently with no way to uninstall them. When I use apps like Ghost Commander to look at other factors of the apps, they have dates from December 31, 1969, and their icons are sometimes just little Android bot heads. I am also noticing that the functionality of the launcher app I use, Apex launcher, doing oddball things like removing apps from my app drawer, moving or removing apps from the home screen, and much more.
I found this post because I am looking for a way to uninstall some apps that I should be able to uninstall, and I saw you had the same app data problem. After about 4weeks of trying to find a way to restore the app data, I am finally accepting that I am just gonna have to let it go. As a consolation prize I have screen shots of my page layouts and where my apps were situated, and I found at least some of my synced Samsung browser tabs and pages which held many months worth of legal research, so not all is lost. This is such a disaster, and to be ready to not let it happen again is almost moot, as this will not likely happen again, and everything important I was working on is not a recurring event. Sooooo, I'm screwed yet again by an act of God. It's gonna be hard to invest much serious effort into trusting my devices to protect what I create. Thanks Samsung. Now may I kindly uninstall these apps that are no longer needed, which came from your cloud, and were installed into my device by you, and are infecting my whole network with something evil? My windows 10 won't even turn on now... I digress ...
