Katapult doesn’t capture the right button, I think KompaktX does as an option to show recents menu feature. You might have to re-enable the accessibility feature for KompaktX, and even Katapult if you were using some of it’s features (the update might have removed them).
For Katapult I’m not sure what is the problem for you, I’ve installed Katapult in 1.6.0 and had no issues installing it or opening it. If you can share some details at this thread.
