There aren't enough details to fully understand this.

  1. There's no log file
  2. There's no link to the file that's problematic, if its a private asset that's ok, just state this we'll work it out when someone works on it
  3. If this is actually an assimp bug then it belongs in the assimp repository and not here.
  4. There is a valid work around listed, does this work?

I'm kind of aware of what they're talking about... but the honest truth is it's so random, it's hard to figure out that root cause. I've troubleshooted this with a few users, who were trying to import their avatars, and the solution 9/10 was to just use GLB. The FBX exporter (or importer?) has been very unreliable, from randomizing Blendshape order to strange actions caused with Blendshape interactions.

I'll shift through some of my stuff and see if I can't find anything. Thankfully, I do know mods do not seem to influence the issue, so if I find one, I'll try to get a copy and create a clean log for bug-reporting purposes.
