CK3 crashes when I try to open the royal court

[Le0tychidas]

I read that some people have the same issue but couldn't find a solution for it.
The precise problem for me is the following description.
When I start a game everything is fine even the royal court works, but after some time passes the game crashes when I click the royal court button. I tried different things to see if it'll make a difference but the outcome was always the same.
I thought it may be bugged when I am at war and click the button to enter the court room, but beeing at war or not still gets a crash in the end.
Then I thought the game file might be corrupted and started a new run. After a while the same happened in this run too.
To summarize the problem after I play for a while the game will always crash when I click on the royal court button.
I haven't tried to play with the royal court DLC disabled, but I like the content and think it's a shame if I am forced to play without it because it crashes the game.
This never happened before and I guess it must be related to the latest update.

I hope that this problem will get fixed and if someone finds a solution please let me know.
Although the new planned content in the upcoming chapter seems awesome, I have to wait with my purchase until this bug is fixed.
