Suddenly very laggy, macbook pro 2012 on sonoma 14.7.1

Used OCLP last wee to update laptop and it has been mostly seamless until today. Booted up after shutting down yesterday (as it seemed to be waking when the lid was closed). Now eveyrhting is super laggy, can't watch video (and that's pretty much all I use this laptop for whilst im working!

Anyone found a fix?
