Hello,

I’ve created a scene in 2025.2 Preview, all worked fine - exported some renders. It started freezing my pc when i changed the Focal Length of the camera to anything above 20mm, trying to render with Path Tracer. It renders with 18mm but anything above 20mm freezes my pc & i have to restart it manually every time.

Thought i’d try 2025.1.1 but it seems like i can’t open my project there because “Unknown version”?! I’ve attached a screenshot.

Any advice would be appreciated.
