Yesterday I upgraded to the new launcher found in the Microsoft Store, after this I uninstalled the old one. I set up my account and used the workaround to fix MCL-19986. Today I opened it up to play offline because that's how the old launcher worked, however it appears that the sign in method has changed effectively removing the offline mode and making it impossible to access the Java Edition. Upon opening the launcher, it displays my Microsoft account. When I click it, an Xbox Live window opens up and says that I am not connected to the internet. There are no buttons to click that would allow me to continue offline. After clicking the X on the window, the launcher says that something went wrong and I am unable to continue. Fortunately Bedrock Edition remains usable as I can launch it from the start menu.
