I found out why the file was crashing LayOut 2025. It’s because of a problem that we have fixed already, but isn’t fixed in the latest release version. It should no longer crash when we next do an update.
For the general problem of relinking one missing file, and LayOut not automatically relinking all of the other missing files that are in that same folder, I think that has been requested before.
@trent may know if that’s something we’ve seen requested.
