Adobe Master Collection Cc 21.08.2020 -x64- Mul... Apr 2026

It sounds like you're referring to a release of from August 21, 2020 (x64, multilingual). This is likely a repack or a "patcher" version from warez groups (e.g., m0nkrus, KpoJIuK, etc.) rather than an official Adobe release — Adobe has never officially released a "Master Collection" for Creative Cloud (they split into individual apps like Photoshop, Premiere Pro, After Effects, etc.).
