Short description of error
Joining two Grease Pencil objects sometimes crashes, sometimes fails silently.

Exact steps for others to reproduce the error

Create a new scene with Animation 2D settings as the default.
Make a Grease Pencil object.
Select it and go into Draw mode.
Draw very many strokes using multiple materials.
Select some of the strokes using shit+left click while "select all stroke points"is enabled.
Strokes > Seperate > Selected strokes
Switch to Object mode
In the Scene Collection, select the new Grease Pencil object, then shift+select the old Grease Pencil Object.
Object > Join

Sometimes it works, sometimes it doesn't. As long as your scene was saved correctly it seems like you can just keep trying the Join command over and over again until you get lucky and it works.

You blender version is very old. See if the problem still exists with a new build from https://builder.blender.org/download/
