Launcher not recognising that i own minecraft after a day

Hi, here reporting a problem with the launcher that has been going on since I migrated my account from Mojang to Microsoft, now the launcher, even the new one is not recognizing that I own Minecraft. Though the launcher will recognize the account when I am online, however I mostly play offline due to internet access issues, and I play Minecraft in places were getting internet access is impossible. From opening the launcher online, and then switching to offline, after a day it doesn't recognize I own the game and instead present the demo mode version. I ask that this launcher bug get resolved properly please, as this is a problem for people who prefer to play Minecraft mostly offline, but it is a major problem for people who have internet issues and can only play the game offline, but can't of this issue launcher not recognizing the account's ownership of Minecraft.
