Lots of people are currently having issues with Trust Wallet. This is an issue with Trust Wallet servers, not a problem with Cardano.
If you are having issues you can restore your wallet in a different wallet interface using your seed phrase or by pairing your hardware wallet. Your wallet is on the blockchain and the software that you use to interact with your on-chain wallet could be thought of as a wallet interface. Trust wallet uses a 12 word seed phrase, this is the list of words you were given when you initially set up your wallet. Eternl, Flint and Typhon support 12 word seed phrases so you can simply install one of those and restore your wallet. Once your wallet is restored in you will see all of your balances, transaction history, unclaimed staking rewards etc. There is no need to unstake or anything like that before restoring.
On a side note, I would recommend using a different wallet interface just for the fact that Trust wallet does not list all of the Cardano stake pools. There are about 3000 stake pools across the globe, trust wallet lists only about 10 of them and they charge stake pools a high fee to join, which is ridiculous. All of the ‘proper’ Cardano wallets interfaces list all of the stake pools automatically. Also, as you are now having problems maybe this is a good opportunity to move to a different wallet interface.
