Recent app issue after one ui6

[Alitahir]

After updating to one ui6 way back in last November my recent app button is not working. It gets better for a day or two then again stucks. Have tried everything except for a factory reset, clearing cache, repairing app, anything I could find on the Internet, even a update came and yet didn't solve this issue. Any lead would be appreciated

What device? 

The One UI V6.0 update has nothing to do with the issue you are experiencing. 

Things to try:

1. Boot into Recovery & Wipe Cache. 
2. Open the Samsung Members app & Click on Support & run the Diagnostics for the Touch Screen. See if you get any errors? 
3. Go to Settings > Display >  Navigation & see if switching from "buttons" to Swipe & back again helps?

2nd last resort, backup your device with Smart Switch & Factory Reset.

Last resort, visit a Samsung Service Centre to get it checked out by a tech.

You tried reparing the app, can you try to uninstall the app, reboot, then reinstall the app? After updating to one UI6, I have uninstalled/reinstalled few apps already for fixing similar app issues.
