Cannot find component in netlist error, followed by crash if project is saved and re-opened.

Description

I have a project that resulted from a CADSTAR import. However, when I try to update the PCB from the schematic, it gives an error. If I save the project and then try to open it, KiCad crashes.

This is the message I get when trying to update the PCB from the schematic: Then if I try to open the schematic after the project has been saved:

Steps to reproduce

1. (1a) Either use the project here: kicad2_1.zip or (1b): kicad2_2.zip or (1c) to recreate it from scratch, follow the steps in #17143 (closed) to import the CADSTAR file from scratch, then if doing (1c), repair the project using PCB Editor->Export->Footprints to new Library then PCB Editor->Tools->Update Schematic from PCB and select Re-link footprints to schematic symbols based on their reference designators.
2. When the project 1a is opened, try to update the PCB from the schematic, and the error message as shown in the earlier screenshot becomes visible. When the project is saved and then opened (or if project 1b is opened), then the crash occurs.
