The easiest way this can be observed is when a launcher profile is played it does not move up the queue in either the profile drop down or the quick play display. Viewing the launcher_profiles.json before and after launching numerous versions not a single change was ever made to any "LastUsed" data values. Creating a new profile on any version, playing it, closing the game, and opening up the json file shows the "LastUsed" value as "1970-01-01T00:00:00.000Z" which is the same date as if the profile were never played. But if the profile is forced to crash during startup by, for example; entering invalid values to the options.txt file, the profile will update "LastUsed" as normal. This problem did persist when reinstalling the launcher, deleting launcher_profiles.json, as well as on a separate computer. I am running Win11 on a fresh install with accurate system time. As someone with hundreds of versions installed (512 to be exact) and almost as many saved as custom profiles in the launcher, this issue is especially painful with how it requires me to scroll through hundreds of versions to the one I want to play.
