I don't know what you implied on "wallet balance disappeared" but you can easily check your wallet balance on any bitcoin explorers, include the blockchain.com explorer. If you see your balance from explorer checking results, your funds are fine. Don't worry about it.

I tried recovering the funds yesterday by creating another wallet, my balance appeared for couple of minutes and disappeared again after receiving and sending coins.

I am confusing with it, honestly. How do you can recover your funds by creating another wallet? Another wallet means another seed, and sure your fund in wallet A can not be in wallet B.
