Ethereum transaction is pending/it's failed and the transaction hash does not show up in etherscan after some time.
In this case, most likely when you bridged your tokens you had selected a wrong Network on Metamask (as Binance Chain or Matic Network).
To be sure, check the transaction hash in a explorer that support those networks.
