It seems that Photoshop versions older than Photoshop 2021 and Photoshop Elements versions older than 2023 will not run on macOS Tahoe 26.
You could just update Photoshop to 2025 or 2026 using the Adobe Creative Cloud Desktop Application.
If you need Photoshop's 3D functions you can install Photoshop 22.2.
