Does it work normally under x11? The log indicates a crash but lacks details. Please run coredumpctl gdb after the crash and type bt to get the backtrace, this will porvide more useful info.

probably some missing dependencies, it works fine on my wayland. need coredumpctl info log to see what crashed.

Hello. I have the same problem as xorly. The sha256sum output is the same as yours, also the files under stm32cubemx2 folder. When I try to start stm32cubemx2 from the launcher, nothing happened but the process systemd-coredum starts and consumes 100% CPU for ~10s, then stops automatically. I'm on wayland+hyprland. Do you need more info?

Have you tried running ./stm32cubemx2 in the /opt/stm32cubemx2 directory? Does the file hash match the one below:

❯ sha256sum /opt/stm32cubemx2/stm32cubemx2

Hi, binary instantly exits without any error code. Did you observe anything similar?
