Launcher can't connect to Minecraft services and I can only play demo

Launcher is in offline mode and cannot connect to the Minecraft services. I can only play demo (on java) and trial (on bedrock) even though I have purchased the java edition about 6-7 years ago and I have received the bedrock edition for free a couple of years ago. Also I can't install the launcher from the microsoft store, it always gives me an error. I can install it only through MinecraftInstaller.exe
