BUG: Icons are disappearing/missing, only back after a PC restart

[pinetreemoonlight]

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

Icons for FlowLauncher entries are missing. This usually happens after a while of using my computer (including hibernating it etc.). The only "solution" that worked so far is rebooting my computer. I tried restarting FlowLauncher, didn't work.

To Reproduce

1. boot PC and use FlowLauncher for a while
2. Icons for FL entries will begin to appear missing

Here is one of the entries I guess, please let me know if you need more details from the log though.

Hi there, is flow stored on HDD/SSD drive or in OneDrive?

[HyroGoth]

i had the same issue a while ago, i reisntaled and everything is normal again, so i assume this is some problem with cached files or something like that. For any dev seeing this, could be worth it to check if this is really the problem, for users with the same problem unistall flow launcher, clear the Flow's folders inside %localappdata% and %appdata% then reintall it. (doing backup fpom your configs is recomended)

Hi, it's stored on an M.2 SSD.

[ShauryaKesarwani]

same thing happening to me as well, i tried reinstalling also twice, and even cleared localappdata and appdata folders of flow launcher, its still no icons and the app also freezes if i search a app, then u cannot bring it back using the hotkey, i need to restart it after killing from task manager

using on a NVMe SSD, no extra plugins other than the preinstalled ones, hotkey setting changed and custom theme from the list of preinstalled one

I also have the same problem. It's probably an issue with the Program plugin. Running a Reindex fixed the problem but I'm not sure whether it's temporary or not.

[Kamilkampfwagen-II]

I have the same issue, reinstalling, clearing cache, deleting user settings, disabling any of the plugins, and running the Reindex option doesn't fix the issue for me.

I found that killing the windows process DllHost.exe (which restarts shortly after) fixes the issue without the need to restart the computer. The command line of said instance is /Processid:{3AD05575-8857-4850-9277-11B85BDB8E09}

I found this about the guid: https://strontic.github.io/xcyclopedia/library/clsid_3ad05575-8857-4850-9277-11b85bdb8e09.html

Edit: Some more info

Interestingly enough, I don’t have anything in the application logs from the time this issue occurs, but I do have this exception about an hour ago
