TLTR: Please enable user namespaces for your kernel because Chromium’s fallback sandbox crashes due to some packaging issue that we cannot solve currenlty.

The crash is actually an issue with Electron’s/Chromium’s fallback sandbox and how we pack the Debian package. It seems that Chromium’s fallback sandbox doesn’t support spaces and our package is saved under /opt/Mark Text/ but we are unable to change this location. I’ll open an upstream issue at electron-builder to be able to use a custom output name such as marktext or to always remove spaces.

Currently you could:

Enable Linux kernel user namespaces to use the preferred sandbox: sudo sysctl kernel.unprivileged_userns_clone=1,
Launch Mark Text with --no-sandbox argument or
Rename /opt/Mark Text/ directory to /opt/marktext but you may change all links and path too. Mark Text will not be uninstalled due to path changes!

Edit: I guess this applies to RPM package too.

I can confirm this issue with Debian 10.5 and Marktext 0.16.2.

$cat /proc/version

The following above mentioned workaround worked for me:
