Might this be OS-specific? I'm on Linux Mint 22 with Qt 5.15.13 and LyX 
2.4.1. My compose key combo (right ALT + " + a to get ä) continues to 
work. It displays the accent character (", ~, `) until I hit the letter 
key, at which point the accented character appears. This is with both 
"traditional" encoding (my default) and UTF-8.
