The MC launcher still does not communicate with the services and is available only on demo mode! V.1.17.1

The problem for my case persists. No fix mentioned by the customer support or here at the moderator note could help solve the problem. I'll be doing this every once in a while in hope of a fix!

Also, it seems that this issue and all its duplicates are being tagged as "resolved". To my knowledge, this issue has not been resolved since I'm still faced with this problem after 2 weeks of migration. Please don't tag issues falsely. Thanks.

Thanks for your reply @NeunEinser. I've read the moderator note and although the hyperlink in the 7th step does not show anything to me (as I've shown in the attachments of this comment), I've done the steps mentioned and I'm still unable to fully play the game.

I have the exact same problem after migrating my account to Microsoft. Now my launcher says that I can only play in the demo version. As you already know, after the migration, you can't log in via the Mojang account anymore, so it means that I went back and logged in via my Microsoft account.

One thing to mention though is I did my transaction via my first email address which obviously was linked to my Mojang account back then. However, I had no Microsoft account with that email address, and I migrated using my second email address which had a Microsoft account linked with it. I think the problem is somehow is related to this.

I've been talking to one of the agents in customer support within the past week to solve the problem. But they finally referred me here. Please don't refer me back to the customer support services. Thanks! 

It seems that I can't use these commands of F3+T/S (for 10 seconds). How is that?
Also, this no-sound startup appears to happen over and over in my occasion and it isn't as rare as it should be. Is it related to the new version of the launcher?

Lights of chunks get updated in OptiFine.
This issue is resolved if you use OptiFine.
