Request: temporary access to last functional Beta build for active project

-I’m working on a nearly completed feature-length film that has been affected by the ongoing Premiere Pro Beta timeline and editing issues.

This regression has been present since mid-December, and has prevented reliable editing on an active feature-length project for several weeks.

I’ve been following the beta builds closely. An earlier beta build, which introduced a revised menu structure, allowed full timeline editing to function normally for me. After a subsequent build reverted the menus back to the previous style, the core timeline editing issues appeared and have persisted for my project, including in the current release.

At this point I’m using workarounds (copying subsequences into new projects) to keep moving, but this is slow and fragile for a project at this stage.

I understand that older beta builds are not normally distributed, but I wanted to ask whether temporary access to the last functional beta build might be possible purely to complete active work, while the current regression is addressed.

I’m not asking for long-term support or rollback as a policy — just a short-term bridge to finish an in-progress project.

Thank you for your time, and for continuing to work on stabilizing the beta.

    TECHNICAL SUMMARY / ROOT CAUSE HYPOTHESIS

    Based on testing across multiple Beta builds, this issue appears to be caused by a regression in how newer Premiere Pro Betas handle missing or incompatible audio plugins.

    When the project references a missing audio plugin (in this case iZotope Alloy 2), Premiere displays an “Audio Filter missing” warning on launch. In newer Betas, this appears to leave the audio engine in a partially initialized state rather than failing cleanly.

    Once in this state, multiple unrelated systems are affected, including:

    • UI responsiveness and menus

    • Remove Attributes and Speed/Duration dialogs

    • Locate File delays (20–30 seconds)

    • Export and XML failures

    • General timeline instability

    Opening the same project in Premiere Pro Beta 26.1 does not trigger this behavior. Saving a new copy in 26.1 and reopening it in a newer Beta restores normal operation, suggesting the older build forces a clean audio engine initialization and/or rewrites a valid audio graph.

    Disabling the affected audio plugin via Premiere’s Audio Plug-In Manager and setting Audio Input to “No Input” prevents the issue from recurring.

    This appears to be a build-specific regression related to audio plugin initialization and cached application/project state rather than permanent project corruption.

    I was able to recover the project by doing the following:

    1. Regressed to Premiere Pro Beta 26.1

    2. Opened an older version of the project from November (before issues began)

    3. The project worked normally in Beta 26.1

    4. Saved a new copy of the project

    5. Quit Beta 26.1

    6. Launched the newer Premiere Pro Beta

    7. Opened the newly saved project copy

    8. Then opened the current/latest project

    After this sequence, the project that was previously unusable (UI lag, Remove Attributes failing, Speed/Duration locked, export failing, XML failing) began working again.

    This suggests a build-specific regression where newer Betas leave the project or application in a corrupted state that can be cleared by opening and re-saving the project in Beta 26.1.

    Additional observations:

    • On launch, Premiere reported a missing audio plugin

    • “Apple Audio Input” appeared as a running app in the macOS Dock

    • Disabling third-party audio plugins and setting Audio Input to “No Input” improved stability

    This does not appear to be permanent project corruption, but a state issue introduced in newer Betas after 26.1.

    NEw version 26.1.10026 fixes nothing Please Please give me acceesss to a roll back tree so i can go back to a BEta version that worked that can help you find what it was the totally broke the program,
