Is it just on that one file ThunderbirdPortable.wim? Are you able to send me that file? Or if it is too large, you could try 'wimlib-imagex info --extract-xml=info.xml ThunderbirdPortable.wim' with wimlib v1.13.6 and just attach the file info.xml. There's a chance that will be enough.
Actually never mind, I don't think you need to bother with either of those. This is on an older CPU, right? I think it's crashing due to the xgetbv instruction being executed when the CPU doesn't support it, due to a compiler optimization that became possible in v1.14.0. I'll fix that.
