I changed and get same problem. Will start a new report.
This issue has not been resolved, don't know why it was marked that way. I have the latest JAVA edition and not running the WIN10 version. Never had any problems until this week.
I've always selected multiplayer then a list of servers would populate for me to choose from. The server I had been playing until all this started had been Hypixel.
Ok thanks. I had forgotten about having to add the server manually. I can now play again. Thank you misterblue28 😃👍
