Hi, I got an issue. I have just clicked to Claim my stacking balance in Core wallet, and after that the wallet was froze and closed. After opening again Core wallet - the balance become empty 
Previous time this issue was fixed by itself by updating a Core wallet, but now wasn’t fixed. How to return my Avax balance ?
Hello is your wallet up to date?
Hi there. It sounds like the cross-chain transfer did not complete moving the funds from the P-Chain back to the C-Chain. The instructions in this article will tell you how to import that tx via Core web (which you can connect to in the in app browser): Core web: What if my cross-chain transaction didn't work? | Core Support
