Two profiles one account

As i was playing on my minecraft multiplayer world with friends at one point i logged in and realized my diamond armor wasn't on but i had spawned in my base (explanation on why i didn't spawn at world spawn or at least my guess later) and then  today i was trying to change a setting but i realized i didn't have operator so i looked and magically i now had my diamond armor back

now my best explanation i can think of at least  there are 2 profiles one without operator and one with operator this is something that i am 90 percent sure about but the word profile isnt really accurate here i guess you  could say 2 minecraft accounts 1 Microsoft account

 and the reason i had spawned in my base was due to me swapping between them without realizing  as there was one time i had spawned in world spawn for no apparent reason

im looking for a way to swap into the account without operator to get armor and the things in my inventory and then make sure i dont continue swapping

( i closed the other profile with diamond armor accidentally and cant replicate it)
