After starting quicklook, the program will exit automatically when the mouse points to the taskbar icon

[HBJ008]

My system is Windows 11 and I was using quicklook normally before, today I was prompted to update to version 3.7.1, so I downloaded the free install version.
After overwriting and unzipping, I opened the program and a small icon appeared in the bottom right corner of the taskbar and the system prompted that quicklook was running in the background.
But when I select a text file and press space button, the preview window does not pop up and when I point my mouse to the quicklook icon in the bottom right corner, the icon automatically disappears and the program flashes back without any indication.

Did you quit QL before installing the update? Did you install in the same directory? Did you reboot?

If all of the above questions can be answered with yes please provide logs. Location is listed in the wiki.

unzipping

I assume you're using the ZIP version. Please check if you have done this step: #1

I think you should use the portable "zip" version, and use the decompressed file of the new version to directly overwrite the upgraded one.
This problem should be caused by a plug-in conflict. Enter the program "QuickLook\QuickLook.Plugin" plug-in folder and delete the following folder should be resolved.
