Rtabmap nav2 bt_navigator error

[GGYU]

Hello Everyone

When I launch, nav2_bringup navigation_launch.py

I am experiencing an issue where bt_navigator keeps crashing unexpectedly.

It used to work fine before, but suddenly it stopped working without any obvious changes.

Can you help me figure out what's causing this and how to fix it?

It feels like some libraries have changed. Did you install new ros packages lately? This could happen when ROS is releasing a new version of the whole stack, but we install only one new package. That could be fixed by doing:

sudo apt upgrade

to update all ROS packages. If you do so, it is safer to also cleanup your build workspace and rebuild all your packages so that they link correctly to all updated packages.
