Multiple, yet minor changes are necessary to make the module work on Drupal 11.
When I run kernel tests, I get these errors and deprecation notices:
There was 1 error:
1) Drupal\Tests\field_permissions\Kernel\Plugin\FieldPermissionType\ManagerTest::testCreateInstance

As I searched through, I did not find a D11 upgrade ticket in the module's issue queue, so thought it was better to collect all the necessary compatibility changes under one roof.
Pipeline green on the merge request, marking as Needs Review.
