Change photos on import

[Deur my lens fotografie]

When I view my photos in file they look good, but as soon as I import them into Lightroom they get blurred and dark, it was not doing that a week ago?

Lightroom (Lr icon) or Lightroom Classic (LrC icon)? What version NUMBER?

Please check to make sure you have not accidentally assigned a preset when you import the photos.

Please show us screen captures of one such photo before import and after import. Use the "Insert Photos" icon to include your screen captures; do NOT attach files.
