Removable Device Icon always open kate

After reinstalling leap 15.4 on my test computer, I run (as usual) some user configuration scripts to configure the software appearance of dolphin, kate, desktop, … .
I can’t say what happens, but now in the “More Recent Device” when I click on the icon option “Open with File Manager” for any usb device, that start kate.

Any help is welcome.

I just realize that if I right-click on a folder , then click on ‘Properties’, then the folder appear as folder but the properties ‘Open With’ is set to Kate.

How to change this ?

The last entry in the list should be “other application”
There you can choose an application and set “Remember Application…”

Check standard application/file association in systemsettings.

Found in ‘System Settings/Applications/Default Applications/’ The property ‘File Manager’ was set to Kate ( I don’t know why . Perhaps a miss click).
After correction to file manager all things return to normal.

Thank you everybody for helping.

Also right click, see the last entry:

OK.
Thank you very much
