Minecraft: Java Edition "Installations

My issue is extremely similar to MCL-19986, but with a clear distinction. I wanted to lead with this so it doesn't get immediately merged and resolved. I haven't trawled the site to see if this specific issue exists elsewhere.

A couple of days I was playing Minecraft: Java Edition on version 1.18 with OptiFine installed. Today, there are only two "Installations" in Minecraft, "Latest Release 1.19" and "Latest Snapshot 22w24a. The aforementioned issue recommended replacing the "launcher_profiles_microsoft_store.json" file with the contents of the "launcher_profiles.json" file.

My folder does not have that first file(_microsoft_store). There are still 32 folders in the "Versions" folder, but none other than the latest are shown in the launcher_profiles.json file. As far as I can tell, nothing has changed about my computer or Minecraft installation since I last played 2 days ago. 

How do I solve this problem? Every tutorial or solution I have found is about the "microsoft{}store" file, which I again don't have.
