3.x not yet compatible with symfony 8.x

[alcohol]

symfony/http-foundation 8.x removed support for calling get on the request object:

Remove Request::get(), use properties ->attributes, query or request directly instead

This is still being used by the resolver controller:

LiipImagineBundle/src/Controller/ImagineController.php

Line 62 in fbd2e18

$resolver = $request->get('resolver');

Since there is no direct requirement on symfony/http-foundation it is possible to install the incompatible version alongside, because the framework-bundle allows both 7.x and 8.x
