Extensions for Joomla! 4.x • Installed J3 plugin to J4 and bricked site

I installed a J3 plugin (Canonical Links All in One) on my J4 site and now I get an error:

An error has occurred.
0 Call to undefined method Joomla\CMS\Application\AdministratorApplication::isAdmin()

I understand the reason but is there anyway to uninstall the plugin or fix this error?

Thanks in advance.
