Metamask + Trezor running very slow

I just imported my trezor into metamask and its fully functional but now the metamask runs very slow. I have the latest firmware and latest version of metamask.

What do you mean by “imported my trezor into metamask”? Did you use the Recovery seed from Trezor in MetaMask?

No. I clicked hardware wallet in the Metamask and then connected Trezor.
