Logic pro graphics suddenly started lagging when using plugins

Hi,

I'm having a real pain of an issue as I'm doing a sound mix for a video. Logic works absolutely fine on my base macbook 16 inch 2020 but as soon as I added a plugin, logics own compressor for example, the whole GUI crashes making the project unworkable.

We've all had laggy graphics when working with logic but this is some new level of lagginess from just one plugin on one audio track. This started happening earlier this week in my music projects but figured that it was just some general cpu lag after having done a lot of work on the computer the days before.

I tried creating a new account on my mac as per this article: https://support.apple.com/en-us/HT200260 and it actually worked, so I'm wondering what I should do since it does not give a solution.

Does anyone have a solution or have you experienced the same thing with plugins being the issue? I have safe-started my mac etc already...
