Hi. I also just solved this issue. For me, I just looked at the first few lines in the error log under Fatal Error. This should show you the name of object that is being rejected (renaming object on top of existing issue). In my case, it was a material located inside my Content Browser. I found it via the location in the log and renamed it. Like others, I had no issues for around 10 days with exact same Datasmith name and location, then some further changes resulted in crashes. I hope this helps!
