Can you enable [devMode](https://craftcms.com/docs/3.x/config/config-settings.html#devmode) and edit the question to share the full stack trace leading up to that error?

Looks like it's choking trying to render an SVG on the Settings page, so my guess is you've got a plugin installed that is trying to display its logo on that page and the SVG is in an invalid format? Or at least a format that Craft doesn't know what to do with. You can try using the `craft plugin/uninstall` command from the project's root to narrow down which one.
