@zxp19821005 reinstalled, now is perfect!!

@GipsyAlt Thanks for your feedback, fixed it. Can you try again ?

Also, there is a minor bug in the desktop file generation. The sed command has a trailing space in the search pattern:

s/AppRun --no-sandbox /${pkgname%-bin}/g

Because of this trailing space, it accidentally eats the space before %U in the Exec line, resulting in Exec=mudita-center%U. This causes launchers like wofi to completely hide the application because it can't find an executable named "mudita-center%U".

Removing the trailing space from the search pattern (or adding a space after the replacement variable) fixes the issue. Thanks again!

Hi, it looks like the application is currently crashing on startup with a missing file error indicating that the linux-x64 serialport bindings cannot be found.

In the prepare() function, the rm -rf cleanup command seems to be accidentally removing the entire prebuilds directory (including linux-x64). The lines in question:

rm -rf \
        "${srcdir}/squashfs-root/resources/app.asar.unpacked/node_modules/@serialport/bindings-cpp/prebuilds/"\
            {android-*,darwin-*,linux-arm*,win32-*} \
        "${srcdir}/squashfs-root/resources/app.asar.unpacked/node_modules/usb/prebuilds/"\
            {android-*,darwin-*,linux-arm*,linux-ia32,win32-*}

Removing or commenting out those cleanup lines in prepare() fixes the issue and allows the app to launch successfully.

Edit: bad formatting

@Scoobert Thanks for your feedback, fixed it.

Hi, validating the hash of mudita-center-4.0.0-x86_64.AppImage is failing for me. I'm getting a different result.
