BUG: About thumbnails

[1208nn]

Checks

• [X] I have checked that this issue has not already been reported.

• [X] I am using the latest version of Flow Launcher.

Problem Description

• Flow fails to get thumbnails and crashes
• Flow crashes when it was still starting but i try to use it

To Reproduce

I don't know the exactly conditions of triggering it, but I can provide some characteristics.

apologize for my poor English

• when crashes, process still in taskmgr but do not show gui
• if crash happens when gui still open (setting window), Microsoft windows tags flow's setting window as no response
• when crashed, process shows in the taskmgr in the background process category and at the time I pressed alt+space, flowlauncher.exe moves to the applications category which means the gui window (search box) created, but i can't see it
• once this happens, flow must be killed and start manually to work, but before a reboot, will still fails to get thumbnails and crashes frequently

---

• sometimes windows file explorer's thumbnail function also crashed
• maybe follow with windows updates installed and need to reboot
• sometimes use sfc /scannow could find something wrong with the windows

---

sometimes when flow was still starting, I pressed alt+space and it will happens but in this occasions, once I kill and start manually, it works well and won't crashes frequently until a thumbnail error

thumbnails not only don't show in the result, also not show in settings, but sometimes when it not show, flow won't crashes.

Screenshots

setting window - plugins

search box

theme switcher preview (background)

store (maybe caused by network, suggest a loading icon to recognize)

no response

Does it happens before?

[1208nn]

Yes

Flow Launcher Version

at least from 1.9.0 to 1.17.1

I started use Flow from 1.9.0.

Before I use Flow, I use Wox. It seldom crashes. I sometimes use PowerToys Run, It seldom crashes, too.

In the latest 1.17.1, sometimes the crash will directly cause the process killed, without the no response statues.
