1 - My minecraft does not enter for some reason, yesterday I upgraded to 1.16.0.68 and entered without internet then I called, logged in my account and it worked.
The next day I opened my minecraft without internet and went to edit my world and closed it, I tried to open it again several times and it didn't work I turned on the internet and entered.

2 - The bug of moving items in the inventory has not yet been fixed, I am reporting this bug since 1.16.0.63
