Images open heavily overexposed in Photoshop Beta 27.10 after update

Photoshop version: Photoshop Beta 27.10

OS: macOS Tahoe 26.5

Steps to reproduce

1. Launch Photoshop Beta 27.10.
2. Open an existing TIFF file.
3. The image appears heavily overexposed on open, despite the file displaying correctly in the regular release of Photoshop.

Expected result:
TIFF files should open with the correct exposure and match how they render in the regular version of Photoshop.

Actual result:
Some TIFF files open with a severely overexposed preview in Photoshop Beta. The image data itself is unchanged—only the rendering in Beta is incorrect.

Additional information:

• The issue began immediately after updating to Photoshop Beta 27.10.
• I've been working with the new Light Adjustment layer recently, so it's possible there's a connection, although I haven't been able to verify that.
