Assets disapearing from Content Browser

Hi,

recently I run into issue, where my assest disapear from content browser, when I restart UE.

For example:

I created Data Asset based on my own Primary Data Asset. But when I restart Editor, Data Asset doesn’t show in Content Browser, nor I can select it as a Variable in blueprint.

In Windows Explorer I can see that .uasset in correct folder.

Note: If I create that Data Asset and assign it to variable and than restart editor, that Data Asset is visible in correct Folder, in that variable is still assigned, but I cannot select that data asset for another variable.

I am using Unreal Engine 5.6.1
