@peter_k can you try following steps?  
If they work, we will add them to the Mautic update docs.

- create a backup of the `composer.json` file (or use your VCS system)
- execute following commands to update the dependencies in your project.

```bash
# remove obsolete themes and plugins
composer remove mautic/theme-nature mautic/theme-mauve mautic/theme-coffee mautic/plugin-citrix

# replace the requirements of all mautic specified dependencies
sed -i -E 's/( "mautic\/.*": ")4\.4\.10"/\1^5.0"/' composer.json

# update the overwritten repositories
composer config repositories.0 git https://github.com/mautic/FOSOAuthServerBundle.git
composer config repositories.1 git https://github.com/mautic/SpBundle.git
composer config repositories.2 git https://github.com/mautic/SymfonyBridgeBundle.git

```

- review the changes in the `composer.json` and adjust if needed
- run `composer update --update-with-all-dependencies` to run the update
