In addition to trevor.dennis' excellent input, I would hold off on upgrading OS -- as suggested by Google AI -- until the dust settles/Apple.com issues a fix for runaway memory usage by [Apple] apps like Calculator.

macOS Tahoe continues to face severe memory leak issues even after 26.0.1

excerpt:
"Apple’s latest macOS release, Tahoe 26.0.1, is drawing heat after users watched basic apps consume eye-popping amounts of memory. One MacBook Air M1 with 8 GB of RAM showed Calculator at 42.31 GB in the Force Quit window. Another screenshot captured Pages swelling to 175.41 GB before the system threw an out-of-application-memory alert. Chrome sat paused at just over a gigabyte while the system crawled. The pattern points to something deeper than a single misbehaving app."

Chech scratch disk 'Photoshop ??? temp' file sizes before and after opening the plugin.  If it increases significantly, then how much free space do you have on the scratch drive?  How fast is that drive?
