The templated Lyra project for 5.5 is missing a reference to IMC_Default_KBM on /ShooterCore/Experiences/LAS_ShooterGame_SharedInput because it looks like IMC_Default_KBM was renamed to IMC_Default. Simply correcting this reference fixes the issue.
Create a Lyra Starter Game (in the launcher, go to Unreal Engine>Library>Fab Library, search for Lyra
If there is no option to select the project version, click on the arrow down and "Remove Local Content", that way you gain access to selecting the version of the project you want to create.
Click on Create Project and select version 5.5
Navigate to the created Lyra folder and open the project
Open level L_LyraFrontEnd
Play In Editor
Play Lyra > Start a Game > Elimination
Check the output log for Error messages
Expected behavior: the template game should start with no errors
Actual behavior: there are some Ensure condition failures
