i dont see this issue exactly, but could be related to MCL-20370 ...

When Ever i open the launcher and navigate to the bedrock portion of the new launcher, it says "not playable on this device", even though i have bedrock edition via the Microsoft Store.

Steps to reproduce:
1. Go to the minecraft store and buy/download Minecraft for Windows + Launcher & Minecraft for Windows.
2. Open the Minecraft Launcher.
3. Navigate to "Minecraft for Windows"

Expected Result: Green button says "Play"

Actual Result: green button says "Not playable on this device"

I do have a work around that im using:
1. go to the microsoft store and open your library.
2. find "Minecraft for Windows", and click on the "..." next to "Launch".
3. click on "Pin to start".
4. Open Start (or hit the windows key) and drag minecraft from start to the desktop.
5. run the shortcut, and Bedrock Edition will run as normal.
