BAT Has Disappeared from the Crypto Wallets Page

About a week ago, I transferred 30 BAT from Uphold to my Crypto Wallet in Brave, and it had been sitting there ever since. I even updated Brave last night to the latest version (through the browser) and it was there last night when I checked before going to bed.
I woke up this morning and went to check my Crypto Wallet, and it is no longer displaying any BAT in the wallet. I have been trying to transfer it from my Crypto Wallet to a Trezor, but haven’t actually clicked on transfer nor paid any ETH in gas to actually do the transfer (I have no ETH in that wallet at the moment.)

Does anyone know how this could have happened or how it may be resolved?

Thanks in advance!
