+With these instructions you can retrieve the stack trace after a crash. Tested on Ubuntu 22.04 LTS:
+
+- Search for `electron@` within [`yarn.lock`](https://github.com/vector-im/element-desktop/blob/develop/yarn.lock) in the Element Desktop repo
+- Note the version, e.g. `version "24.3.1"`
+- Download the debug build for the same version from [here](https://github.com/electron/electron/releases/)
+- Extract the contents of `debug` from the archive to `/opt/Element` (or `/opt/Element-Nightly` for the nightly version)
+- If Element crashes let the system create a crash report
+- Open a terminal
+- Go to `/var/crash`
+- Run `apport-unpack _opt_Element-Nightly_element-desktop-nightly.1000.crash /tmp/elecrash`
+- `cd /tmp/elecrash`
+- The stacktrace is located in the `Stacktrace` file there
+
 #### Debug builds
 
 On most Linux builds, Element doesn't include debug symbols, which means it's still quite hard to tell what's going on - the crash dump won't contain the names of functions that the program is in, just which libraries are being used.
