When my launcher is set to latest snapshot the game loads into a version of the game without any 23w12a features (so the same features as 1.19.4) but the home screen says snapshot and the F3 menu says snapshot 23w12a.

When selecting 23w12a in the launcher it launches into 23w12a properly

As far as I know this is the launcher from minecraft.net, not from the microsoft store (idk if there's even a difference)

Images:

Title screen with 1.19.4/snapshot (says 1.19.4 without the snapshot part on actual 1.19.4 and says 23w12a/snapshot on actual 23w12a)

F3 menu that says both 1.19.4 and 23w12a (says only one of the two on the working versions)

No 23w12a features (I had to turn on experimental features to even get the suspicious sand and experimentail features don't even exist anymore in 23w12a)
