I recently upgraded to connector 8.1 and .net 7 and started getting this error too.

In my case I have several background processes that attempts to initiate the connection from multiple threads in parallel.

Solution: Instead of downgrading the version i have solved the problem by initiating the first connection to mysql at the startup itself. This way the pool is created from the main thread and then there is no issue of requesting connection from multi threads.
