Super Contributor.qip files for subsystems are generated when the top-level system is generated and should be pointed to by the top-level .qip. You don't need to generate a subsystem separately. Of course if you make a change to any system, then yes, you'd need to regenerate.
Why is Pro not an option?
Again, the file is probably corrupted. Converting to Pro may be fixing the issue which is why it opens correctly in Pro.
Yes, you can try creating a new .qsys file.
Occasional ContributorThe Pro edition is currently not an option, because we have to reuse a large amount of older IP cores that were originally designed with the Lite and then migrated to the Standard edition. I have done a quick test and opened them with the Pro but promptly received error messages after the migration.
I have created the top level .qsys file from scratch now and it didn't seem to improve the performance but after that I generated HDL for the largest subsystem and let the platform designer create a hw.tcl for this subsystem that I then instantiated in the top level system. This seems to improve the performance, but I can not yet confirm it.
The next step will be to create this largest subsystem again from scratch to analyse whether maybe this file is corrupted.
