Bech32 starts with Bc1. Legacy, for example, starts with 1. There is another that starts with 3.
Electrum wallet support Bech32 addresses and even stopped to show Legacy and Nested Segwit addresses a long time ago. There are other wallets that support Bech32 as mentioned in Bitcoin Wiki. https://en.bitcoin.it/wiki/Bech32_adoption

Electrum does not support addresses like the one you mentioned: 0x9. That seems like an Ethereum or Binance Smart Chain address.
Make sure you downloaded Electrum from the real website, otherwise you might have some scam version of the wallet! https://electrum.org Is the real link!
OP needs to be careful practically when download and install any wallet software.
