When i add color lookups photoshop crashes for 1 minute

[Ilgar_Dadashi]

when I add color lookups photoshop crashes for 1 minute, it's very hard to experiment with color lookups, because every time I switch in color lookups I have to wait 1 minute, this problem happens after updating to CC 2017.

Hi IlgarDadashi,

Please update Photoshop to the latest version 2017.1.1 also, you may try and reset the Photoshop preferences back to defaults.

Refer:  Preferences in Photoshop

Let us know if that helps.
