P: Adobe Premiere Pro v26.2.0 (Build 65) Severe System Hang when Accessing Menus and Panels
Bug Report: Severe System Hang when Accessing Menus and Panels
App Version: Adobe Premiere Pro v26.2.0 (Build 65)
Issue Category: Performance / UI Responsiveness
Status: Recurring / Degrades over time
System Specifications
Processor: AMD Ryzen 9 5900XT 16-Core Processor (3.30 GHz)
RAM: 64.0 GB DDR4 3600 MHz
Storage: WD_BLACK SN770 NVMe SSD (Firmware: Latest/Current)
Operating System: Windows 11 Pro
OS Version: 25H2
OS Build: 26220.7872
Issue Summary
Opening any top-level menu or interacting with specific utility panels (Properties, Project Manager, Subtitles) causes Premiere Pro and the entire operating system to freeze for 5 to 7 minutes. The issue is cumulative; the application becomes increasingly sluggish the longer it stays open, eventually requiring a full restart to regain functionality.
Steps to Reproduce
Launch Premiere Pro v26.2.0 (Build 65) on Windows 11.
Perform standard editing tasks for a period of time.
Attempt to open any top-level menu (e.g., File, Edit, Clip) or the Project Manager.
Alternatively, use the Properties menu to adjust subtitle parameters, frame positioning, or zoom levels.
Expected Result
The UI should remain responsive, and menus/panels should open instantly without impacting system-wide stability.
Actual Result
The application stops responding immediately upon clicking a menu.
System-Wide Lockup: The entire OS freezes for 5–7 minutes. During this time, no other programs can be interacted with.
Performance Degradation: The "slug-like" behavior worsens over time during a single session.
Normal operation is only restored after a full application restart.
Additional Observations
Workaround Limitation: While keyboard shortcuts work initially, they do not prevent the freeze once a mouse-driven menu is accessed.
Hardware Note: Given the high-end specs (Ryzen 9 5900XT, 64GB RAM, NVMe SSD), this is clearly a software/UI conflict rather than a hardware bottleneck.
Note for Support: This issue significantly impacts professional workflows as it forces a complete system halt multiple times per hour. Please investigate potential memory leaks or UI rendering conflicts in Build 65.
