Cannot Open FCP File

The latest version of FCP is not allowing me to open a .fcp file.
Error: List Index Out Of Bounds (7209071). TFontContainerRange is 0..156
This font file contains diacritic characters.
Can anyone help please?

I can confirm the issue. No doubt Erwin will reply soon.

Moved topic to bug reports.

I don’t think it is related to the latest version of FontCreator. To me it seems the file is corrupt.

Thanks Erwin. I’ll see if I can find an earlier backup of the file and let you know how I get on.

I’ve tried opening 2 earlier versions of this file, and both failed to open with the same error. This confirms that something has changed in FCP rather than a corrupt file. Could you please look into this further?

What version of FontCreator can open them?

The last time I edited this file was 27/07/24, so one of the versions between then and the latest has broken it, but as I’m only running the current version I’m sorry but I cannot give any more information than that.

We have a strong indication the file is corrupt. Especially while we do not know if there is a version that can open the file.

If it happens again, it would help if we can somehow reproduce the problem.
