I can’t figure it out the solution. The error seems point to library or data corruption. for op.
Odd enough the app image should not have issue with sqlite,. Libwebgtk is known not packed with the appimage since it already pre-installed in most ubuntu distros.
Just for the safe side restart computer. try redownload the app image. and make it executeable again. and execute it.
Oh interesting keyword there. “manager.upgrade.process”
Question. do you download latest appimage? when the last time you upgrade from the old version which is not the appimage?
