There has also been an issue from the start of this mod where convoys returning to port would get stuck.
They should delete when the reach their last waypoint.
If they get stuck before the last waypoint - they can create a jam.
Then when the next convoy arrives - the jam get worse.
This can cause hundreds of ships jammed at the mouth of harbours and when your boat gets to within 30km and the game has to draw all these ships - ctd.
This issue is very rare - I have fixed many ports by setting a balance between delete area and how far into ports this is.
Can you tell be port, date and campaign this is happening in
