Comment 1 Aaron VonderHaar 2022-03-21 03:33:06 UTC 
I was able to reproduce this with the following steps:

1. Reboot the system
2. Log in with a user account using Latte Dock
3. Right click the dock and click "Add widgets..." for the first time after logging in
4. The search field in the widgets list doesn't have input focus like it normally should
5. Start typing a search term
6. Latte crashes (see stack trace in original report)

After it crashes and automatically restarts, adding widgets seems to work okay on subsequent attempts until logging out.
