The launcher opens fine, but actually pressing "Play" results in consistent failure. I tried it on an older version (1.18.?) and it worked, but 1.19.4 has not. Firstly, I'm greeted by the message that "Accounts in Microsoft Store and Launcher do not match." Of course, this is not true. Next, when I click past that and try to open the game, the download makes no progress, and then I'm met with a random error. The one I have been able to reproduce the most says:

Failed to download file.
Name: text2speech-1.16.7.jar
URL: https://libraries.minecraft.net/com/mojang/text2speech/1.16.7/text2speech-1.16.7.jar
Error details: Send failure: Connection was reset
Filename on disk: text2speech-1.16.7.jar
Path: C:\Users\DatCa\AppData\Roaming\.minecraft\libraries\com\mojang\text2speech\1.16.7\text2speech-1.16.7.jar
Exists: Nonexistent

They've all been "Failed to download file" errors. I've formatted my PC, reset my internet, and made sure firewall isn't blocking anything. As far as I can tell, this is an error that is not occurring on my end, as I am able to download anything else.
