Black screen and Freezes during a Match: NullPointerException

Hi, during matches i have random blackscreen and all the match freezes... i'm also unable to restore the game. If i reduce the XMage window to an icon, nothing reappears and i'm stuck in a completely black screen. What can i do? I'm on Windows 11, latest release, Beta Server. I leave here the log:

Error type: General error - NullPointerException

Client version: 1.4.57-V2 (build: 2025-04-19 14:23)
Java version: 1.8.0_201
Default charset: UTF-8

NullPointerException - look at server or client logs for more details

Stack trace:

Start at mage.remote.SessionImpl.getTableChatId line 738, then follow the call through SessionHandler.getTableChatId, TableWaitingDialog.showDialog, and CallbackClientImpl.joinedTable. Reproduce the match-join or table-waiting flow using the supplied Windows 11 and beta-server context; done means the NullPointerException no longer causes a black, frozen, unrestorable match.
