My Galaxy S6 Tab LTE has been working for some time with no serious problems. A few days ago I was notified of an upgrade to take me to Android 11. The upgrade took some time but completed without reporting any errors of any kind. Upon restarting I had to learn some new settings etc but it all seemed to be fine.
I've got a very large number of apps on the tablet which have all been working fine. However I noticed that some apps (which I have been using for many years) no longer work. There is no error message of any kind but, after clicking the app to start it, there's a quick flash suggesting it's starting but within a split second it stops. Due to the huge number of apps I have, I've not yet checked each one of my 500 odd apps, but the ones failing include:

These have all worked perfectly before. My initial thought was to uninstall/reinstall the apps and reboot the tablet but the problems remain. I then thought maybe these apps need to be corrected by the developer to work under Android 11. However I have a Galaxy A21 with pretty much a 100% identical list of apps. The A21 has also just been upgraded to Android 11 and all the same apps still work perfectly on the A21.
Has anyone else encountered similar problems or can suggest any action I might take to try to overcome the problems with the apps failing on the tablet?
