I have made this bug report in the past, they said keyboard and mouse support will be added in 1.19.1, yet there is no support for it on 1.19.2, in minecraft preview 1.19.10.23, keyboard and mouse works perfectly fine. I want an explanation for this

This is a duplicate of your previous report (MCPE-156685)
As mentioned in a comment on that report, keyboard and mouse support has been added in 1.19.10. Please see https://feedback.minecraft.net/hc/en-us/articles/6465669193997-Minecraft-Beta-Preview-1-19-10-20.
The 1.19.10 version is still in Preview and has not been released yet in a non-Preview version. 1.19.1 and 1.19.2 are "earlier" versions than 1.19.10 (all digits in release numbers matter, so both 1 and 2 are less than 10).
