Website shortcuts on the homescreen are gone on Android 11 - how to restore them?

I lost all my website shortcuts on the homescreen on Android 11. I didn't know of **this bug** due to which all web shortcuts on Android can suddenly disappear at any time. **How to get the shortcuts or the link URLs of these shortcuts back?** Also see [How do I backup my website homescreen shortcuts?](https://android.stackexchange.com/questions/224433/how-do-i-backup-my-website-homescreen-shortcuts/256780) where I described the two things I tried. Briefly, in Xiamoi Mi Note 10 (MIUI) under Backup and restore one can backup the the System launcher. The problem is that I'd also like to restore things between my last backup and now if possible because it's been a while since I did the last backup of the Systemlauncher and that when restoring from that file, the homescreen shortcuts are not restored. When copying the backup file located in /MIUI/backups/AllBackup to a Linux computer and running strings /directory/AllBackup/timestamp/Systemlauncher\(com.miui.home\).bak > ~/backupfile.txt I can read the file with a text editor but the actual links seem to be encrypted or simply unreadable. When I search for com.miui.home.launcher.DEEP_SHORTCUT I can only see the titles of the shortcuts and there even are some problems with that. The mobile Web browser didn't warn about this bug which is still not fixed by Google (or whoever is responsible for closing it) so I think most people only learn about this once they lost all shortcuts so that they start to use other methods to save websites like browser bookmarks. I have the latest Android updates and I also have problems deleting app caches. I had many shortcuts and many of them were important so I need them back. **How to read the links in the .bak file?** Often the title is incomplete and they all have a shortcut_id but that ID appears only once in that file.
