Photoshop not Working super slow and lagging - why? Versions 2025 / 2026 I own a full licence

Why is my Photoshop so slow now that I cannot work? I changed all settings in preferences as suggested online, but no improvement

And I cannot find a way to download an older version, e.g., 2023 Photoshop, the oldest on the Creative Cloud seems to be 25.0 and it doesn’t work for me (super slow and lagging)

I have a 2019 MacBook Pro, more than 200GB of memory available and the system updated to the Tahoe last version

What can I do? I need Photoshop for work. I have a full Adobe licence and I am stuck

Thanks
