'Invalid Sender' Error when sending funds

*getting alot of scam replies, anyone with insight able to help?
My metamask is presenting me with the following error when trying to send funds to another wallet, or interact with defi protocols. This error occurs on ETH, BSC & Fantom Opera chains.

[ethjs-query] while formatting outputs from RPC ‘{“value”:{“code”:-32603,“message”:“Internal JSON-RPC error.”,“data”:{“code”:-32000,“message”:“invalid sender”}}}’

I have restored my phrase on another windows PC, however, this error still occurs. I am using Brave Browser on both PCs.

This happend 1 day after connecting my wallet to the avalanche network, however, I was able to bridge assets across before the errors starting coming through.
