Hi,
I have been offered the following advice to resolve problems running an AppImage:
I ran into the same issue with OrcaSlicer and QidiSlicer.
I found a "workaround" on the Playdate developer Forum they run into the same issue with their software.
The following commands worked for me with Orca- and QidiSlicer:
sudo add-apt-repository -y "deb http://gb.archive.ubuntu.com/ubuntu jammy main"
sudo apt update
sudo apt install libwebkit2gtk-4.0-dev
Just replace libwebkit2gtk-4.0-dev with whatever 4.x version you need.
Here the link to the original Forum post:
