Unable to start
This is the latest in a string of bugs I've experienced. I played Java Edition Modded with Curseforge for years and experienced no issues. As soon as I had to migrate to a microsoft account I've been basically unable to play. I've uninstalled and reinstalled Minecraft, Java, Curseforge etc. multiple times, deleted all relevant files on my computer cleared out my recycle bin and still i get this error message. My internet connection is fine. Occasionally it tells me I have a corrupted installation, but for the life of me I can't figure out why. Please help.
