"GdkPixbuf-CRITICAL" error with the .appimage file on Linux Mint

[Mr-Oca]

Hello !
I'd love to use your tool, but I can't find a way to make it work.
I'm on Linux Mint and when I run the .appimage file through the terminal with

/home/user/Desktop/LikeTaskManager-x86_64.AppImage

I have the following :

qt5ct: using qt5ct plugin

setting auto DPI screen scale factor

instantiating MainWindowI dont know what to do

Full log : log.txt

And nothing happen (no window opening or else).
I'm kind of knew to Linux and I dont know what to do.
I looked over the internet but couldn't find anything helpfull.
Can you help me please ?

i sorry to hear it does not work for you. I never encountered such a problem. The log indicates though an incompatibility with oyur desktop theme.

Does the same issue occur, when you change to a differnt theme in your mint linux?

[Mr-Oca]

I just saw that I never answered you : /
I changed back the theme for the default one, and now I have only this :

setting auto DPI screen scale factor
instantiating QApplication
instantiating MainWindow

And still, nothing happens.

finally found some time trying to reproduce
testet with linuMint 21 with cinnamon as well as mate. both work without issues. so the issue is not inherently tied to linuxmint
