ros2genmsg is failing after a updating database of messages and running a second time. The custom folder is being updated with new messages that are needed for the project. The ros2genmsg is run again with the folder destination but error with the following:
Error using ros.internal.ROSProjectBuilder/buildPackage (line
534)
Error building package: build log.
Error in ros2genmsg (line 241)
buildPackage(builder, [], ' --merge-install',
colconMakeArgs); %other messages might need to be present
in the same directory
I'm using: '9.10.0.1739362 (R2021a) Update 5'

Thanks for those logs. The main issues are in the stdout_stderr.log file and all look like:
make[2]: *** [CMakeFiles/vision_msgs__python.dir/build.make:104: CMakeFiles/vision_msgs__python.dir/rosidl_generator_py/vision_msgs/msg/_bounding_box3_d_array_s.c.o] Error 1

I think that looks similar to an issue I've seen before that ended up being a problem with Dashing's version of rosidl_python. If you update to R2022a, it supports ROS 2 Foxy, which has a fix in-place.
