Ever Since I tried Lens Blur, Lightroom Classic is Running Super Slow

[LosFelizGirl]

I tried Lens Blur on a few different images, it seems to super bog down my system, so I end up not using it. The weird thing is, even after I unckeck the "apply" box my system still runs super slow.

 If i do anything in develop mode I get the spinnig beach ball, or a super long delay time before seeing the results of whatever I'm doing. For example, if I drag my contrast slider down,  I don't see the slider move to the left unill about 6 seconds after I drag the slider down.

-This only happens when working on the images where I auditioned Lens Blur (but end up not using it)

How do I fix this?

Chip: Mac M1 Max

See if purging the Camera RAW CACHE helps.

Thanks for your reply. I have done this, didn't help.
