Adding effects into track makes davinci useless

Hello,
When i add effects to whole track in [EDIT] Fairlight page in mixer window, Davinci studio start chocking and its useless. I must wait few seconds after click to see reaction.

It starts with newest davinci studio version.

Era D plugins
Windows 10
i7 8700
64GB RAM
1060 GTX

Which GTX 1060 do you have, 3GB or 6GB?

I'm confused. Are you working in Fusion (visual effects) or Fairlight (audio effects)?

Try one of the resolve build in audio effects, verify that works.
then try a different third party effect.
it might be an issue with the ERA D effects but we dont have enough info from you to test, nor the effects.
