SF6: Error using Filters: Symfony\Component\PropertyAccess\PropertyAccessor::isReadable(): Argument #1 ($objectOrArray) must be of type object|array, null given

[BOAWEB]

Describe the bug
I upgraded to SF6(.0.1) and EasyAdmin 4.0.1. When using the filters in the backend (through the modal window), I get the following error:
Symfony\Component\PropertyAccess\PropertyAccessor::isReadable(): Argument #1 ($objectOrArray) must be of type object|array, null given, called in vendor/easycorp/easyadmin-bundle/src/Field/Configurator/CommonPreConfigurator.php on line 93

To Reproduce
SF6(.0.1), EasyAdmin 4(.0.1), set filters in Crud index.

I've got a bit of a hack to work around this:

    public function renderFilters(AdminContext $context): KeyValueStore
    {
        if (null === $context->getEntity()->getInstance()) {
            $context->getEntity()->setInstance(new (self::getEntityFqcn()));
        }
        return parent::renderFilters($context); 
    }

Thanks for reporting. Please, try the fix proposed in #4910 (it fixed the problem for me).

@javiereguiluz I can confirm this now works in SF 6 (PHP 8.1) with the latest release 4.0.2.

Closing as fixed in #4910.

Still experiencing similar issue

Symfony\Component\PropertyAccess\PropertyAccessor::isReadable(): Argument #1 ($objectOrArray) must be of type object|array, null given, called in /app/vendor/easycorp/easyadmin-bundle/src/Field/Configurator/AssociationConfigurator.php on line 269

php: 8.1
symfony: v6.2.2
easyadmin-bundle: v4.4.5

Adding "hack" mentioned by @timsweb helps,
