Opening Premiere Team Project triggers error that says update is required. However, there are no updates available in Creative Cloud

Hello ​@christie_0431 

Welcome to the Premiere Forums. We see you are on Premiere 26.5.2 but we could use some information about your system too.

• Operating System: Specify Windows or macOS, along with the version.
• Chip (Mac Only): Specify which M-series Chip or CPU/GPU combo.
• GPU and Driver (Windows only): Please let us know your video card and driver version. We recommend updating to the most recent version; for NVIDIA users, we strongly recommend the Studio version of the driver.

With Teams projects it can also help to know some of the basics of your team member’s systems too, like the mix of Windows to Macs and if anyone else on the Team is having this issue. If not, is it possible some of your team members are editing this Teams project in Premiere Beta? You can download the Premiere Beta from the Creative Cloud in parallel with the current release version. If you’re able to open it in that version, it’s possible a Team member may have inadvertently upgraded it. Premiere Version 27 will be released soon, however, but checking if you can open it in Beta would be informative.

Hoping to help,

Amy
