Research direction
Investigate the query processing logic in Flow Launcher that handles user input. Focus on the 'w' key specifically, which causes a freeze. Look at recent commits or comments in issue #3991 for possible causes. Add logging to trace the freeze in the input handling path, possibly in a method that processes queries asynchronously. Check if the freeze is related to searching or indexing, and consider profiling to identify the bottleneck.
