Problem 1
- Root composer.json requires drupal/link_attributes ^2.1, found drupal/link_attributes[dev-2.x, 2.1.0, 2.1.1, 2.x-dev] but these were not loaded, likely because it conflicts with another require.
Problem 2
- droptica/droopler is locked to version 8.3.3.0-rc3 and an update of this package was not requested.
- droptica/droopler 8.3.3.0-rc3 requires drupal/link_attributes ^1.1 -> found drupal/link_attributes[dev-1.x, 1.1.0, ..., 1.x-dev (alias of dev-1.x)] but it conflicts with your root composer.json require (^2.1).

Would it be possible to have an update on this please?
You used the Droopler template (https://github.com/droptica/droopler_project) in version 8.3.3.0-rc3, and to fix this issue, you first need to upgrade droptica/droopler from 8.3.3.0-rc3 to 8.3.3.0. In this version, the link_attributes module has already been updated to version ^2.1
