We’ve registered this occurrence as the information provided always helps, especially if similar reports occur. There won’t be any disclosure regarding this particular issue as it’s not possible to determine what’s causing it without looking into the save itself.
Unfortunately, due to platform related limitations which are outside of our control, you’re unable to share your save with us so that we could look into its database and determine if it’s corrupted or if there’s any other issue preventing it to load.
We’d advise, however, to try and revisit that save in posterior patches, in the eventuality that the loading issue is not related to data corruption and further optimizations do allow you to successfuly load into it. We do apologize for the situation.
