Dynamic import in extension crashes gnome-shell 44.1 at login
Using dynamic import() syntax in an extesion causes the Gnome Shell to segfault and crash when loading the extension at startup. The crash happens at libmutter-12.so as can be seen in the reduced logs below or in the full logs.
Stack trace in journalctl.

ELF object binary architecture: AMD x86-64
May 11 16:40:04 marmis-arch systemd[1]: systemd-coredump@0-810-0.service: Deactivated successfully.If the extension is enabled via gnome-extensions or gnome-extesions-app, it should work as expected. However, when the extension is automatically loaded via autologin (couldn't test via normal login), then gnome-shell crashes and needs to be restarted without extensions.
Example extension
The following code can be placed in an extentension.js.
function init({ metadata }) {
const { uuid } = metadata;
function enable() {
log(`Enabling ${uuid}`);
import('./file.js').catch((reason) => {
log(`Error ${uuid}: ${reason}`);
if (reason instanceof Error) {
logError(reason, uuid);
}
});
}
function disable() {
log(`Disabling ${uuid}`);
}
return { enable, disable };
}It doesn't matter if the module ./file.js is present or not, the shell crashes either way.
