"Unable to verify what products you own" and "Realms request failed" error messages

I receive both these errors when opening the launcher. I can play both Java and Bedrock editions in singleplayer, but Realms will not load and neither will the marketplace. On the Realms page on minecraft.net, the message, “Oops, something went wrong. Please try again. If issues persist, please contact support.” appears. It also says it can’t load my minecoin balance. Here is the bug report from the launcher: https://sending.pastefor.help/upload/7465ccaf

I also receive the error, “Oh no! Something went wrong, and we couldn’t connect to the Minecraft services. Please connect to the internet to refresh your offline access.” on launcher opening. But after hitting the ‘Try Again’ button several times, that message goes away and the play button no longer says offline.

For additional background: I’ve had this account for 10+ years, and had to merge from Mojang to Microsoft when the takeover happened. I’ve always found the Xbox launcher to be a pain, but for the past several years have had no issues with launching Java edition and joining modded multiplayer worlds. This is the first time I’ve ever touched Realms or Bedrock. I’ve deleted and reinstalled the launcher and .minecraft folder to no avail.
