Start11 does not appear to like being woken up.
I am currently using 2.5.2 but I've been experiencing this issue since 2.5 came out. I have a single monitor and dock the Start bar on the left with auto-hide turned on. I've found that whenever I wake the computer, Start11 is not responsive. Sometimes I only see an outline. Sometimes it will un-hide but nothing is clickable. I have to invoke the Windows search using the standard hot key, type into the search to have it locate the Start11 app, run that and go to the Taskbar page of the config, and click Restart explorer. This also happens on the initial load of Windows. I'm using Windows 11 Home version 24H2.
