Comment 7 for bug 1984143

I'm also unable to launch this app, but for me it started on first installation of it (so, I have never been able to launch it successfully). My error from running it in the terminal is also slightly different:

```
$ extension-manager

(extension-manager:8781): GLib-CRITICAL **: 13:35:31.156: the GVariant format string 'd' has a type of 'd' but the given value has a type of 's'

(extension-manager:8781): GLib-CRITICAL **: 13:35:31.156: g_variant_get: assertion 'valid_format_string (format_string, TRUE, value)' failed

I'm also using Wayland and Nvidia driver version 515.65.01.
