Liquify tool does not work.

I open the liquify tool on the PSD and apply what I want but when I click on save the modifications are simply not applied. My App is up to date.

Hi @Izo Junior | SAMPPA 

Try the following: 

1. Go to Preferences/Technology Preview and check "Disable Native Canvas" - Restart Photoshop. 
2. If you hold down the Alt key when you select Filter > Liquify... does it work correctly without crash?
