Same here, still can't launch Appimages and now it's worse because .desktop files are opened on Kate instead of launched as well, although I'm on 21.04.3 stable for now because I'm testing DNF on Tumbleweed and, so far, it doesn't do well with KDE Unstable Repos.

Could old configs on Plasma be the cause of this? For me, the dialog "For security reasons, launching executables is not allowed in this context." keeps appearing whenever I try to open an Appimage.

Currently on Dolphin version 22.04.2. Double-clicking to launch AppImages, .exe's or .sh's work normally. However, right-clicking then running isn't possible as there is no 'Execute' option listed in the menu. Same with .desktop files; they work if you double-click, but you cannot right-click and execute.
