Cannot Access Plugins Menu – Fatal Error on Mem Size

Hi All,
I get the error above that doesn’t allow me to access the Plugins menu in WP. I’m guessing this happened after I upgraded a plugin, but not sure which one.

Any clue what I should disable through my site FPT since I can’t do it through the WP UI?

Or I could rename the whole folder? (I have a good deal of plugins)
