Adobe Photoshop Lightroom Classic 2021 V10.4.0 «CONFIRMED ✔»

Because Adobe only keeps the latest version and the immediate previous version in the Creative Cloud app by default, obtaining v10.4.0 requires using the Creative Cloud Desktop App’s “Other Versions” feature.

Lightroom Classic is subscription-only. However, if you have an active Creative Cloud Photography plan, you can downgrade to v10.4.0 via the Creative Cloud Desktop app’s "Other Versions" menu. This allows you to revert from a buggy newer version without losing your catalog (though upgrades are one-way; v11+ catalogs cannot be opened in v10.4.0).
