Short description of error
Opening a file containing a cryptomatte node with a matte_id instantly crashes Blender.

Exact steps for others to reproduce the error

Factory startup
Enable Cryptomatte object pass
Go to the Compositor, check Use Nodes, add a Cryptomatte node, and connect it to the input and output Viewer and Composite Nodes.
Render
Pick the Cube. I tested, and you can even deleted the other nodes. The matte_id being in the node when the file is saved causes the issue.
Save the file and close Blender.
Open Blender and try to open the file.
Crash.

Steps 1-6 are already done in this file, just try to open it:
