I have the same issue, you can fix by your own this issue renaming the file launcher_profiles_microsoft_store.json to launcher_profiles.json. After the forge/optifine installation remember to rename back the file to his original name. This Works for me. Note: This is a temporary fix until the devs fix this issue. (I don't know why microsoft added the "microsoft-store" label after most of the minecraft files making everything seemly imcompatible)
