application launcher fails to complete

hello

i'm having trouble launching the application. it only works maybe `1` time out of `10` and never seems to retain my login information

it usually hangs entering my login and clicking on the `Let's Go` prompt on the `Welcome to XBox` screen


below is the output from running it on the command line
```
$ flatpak run com.mojang.Minecraft

```

i usually try to leave it on that screen for about ten minutes before giving up and killing all the processes because i can't get them all to go away simply by closing the window

i've also had limited success deleting the following directory but it's not a silver bullet

```
$ rm -rf ~/.var/app/com.mojang.Minecraft/
```

i wondered whether my issue may be related to https://github.com/flathub/com.mojang.Minecraft/issues/116 so i added the two overrides as below. but this doesn't appear to have made much difference

```
$ flatpak override --show --user com.mojang.Minecraft
[Context]
sockets=session-bus;

[System Bus Policy]
org.kde.kwalletd5=talk
```

i'd be grateful for any help with this. my system details are below

```
$ flatpak info com.mojang.Minecraft

Start by reproducing the intermittent login hang with `flatpak run com.mojang.Minecraft` and review the reported cache, lock-file, CEF, and sandbox messages. Compare behavior after removing `~/.var/app/com.mojang.Minecraft/` and applying the shown Flatpak overrides; done means the launcher consistently completes login, retains credentials, and exits cleanly.
