I can play only built in sounds, mine are just silent UE5

Hi there! A few days ago I wanted to free some space on my system disk. So I found instruction that says to delete DDC folder in appdata/etc… and set other folder in settings for that. I made that. And I have got problems with textures and my sounds just not working anymore. Built in sounds is okay. But any other sound just not playing (editor, content browser, game). In new project the same. How is that? Help me, please!
