Hello Wolve and welcome to the Discourse!
If anyone knew about a bug as crucial as this it would probably be resolved already knowing Team Radiant, but in the meantime you could try filling of a bug report using the format shown here: Welcome to the Bug Report Category!
Also make sure to get the log file as bugs crashing the game often log an error that is critical towards solving them. See this page for how to find the log file.
