I am having the same issue here and the proposed solution by @mahtab_alam fixes the issue.
My setup:
- Content Type with Entity reference revisions field for Reference type: Paragraph.
- Paragraph with long text field and MaxLength enabled.
Currently in the dev branch there is a space between the '^' and '10'. This is causing an error in Drupal 9.5.
The 'core_version_requirement' constraint (^8 || ^9 || ^ 10) is not a valid value in modules/contrib/simplesamlphp_custom_attributes/simplesamlphp_custom_attributes.info.yml
I can confirm that in v9.5.4 I am still experiencing the same exact issue as DamienBurke → in #9 🐛 Cannot remove media on field, when there is a custom validation error Active .
