Win10 w/ Threadripper 3960X ( and two RTX 1080 Super GPUs and 256GB RAM (85% free)

I'm aligning ~36000 images in one chunk and trying to figure out why metashape is being super unresponsive and barely using any resources (1 core). When trying to check where the process is, I found that the screen has not updated for about 6 hours (08:41:11 local time and it's 15:22 right now), and the logfile is being written very slowly (currently 44h behind at 11:07:23).

logfile is writing to a SSD with 500GB of space. I thought it might be too big (77MB) so I copied & cleared it but write speed didn't change.
Resource Monitor shows 7 root threads waiting for a child thread, and 358 associated handles, which I'm happy to provide if they'd be useful

 the last line showing in the console (which is currently unresponsive) is bolded and underlined below. The logfile lines being written look like it's in the same process:

Hello andyroo,

Do you have "fine-level task subdivision" enabled and whether the project is saved in PSX format?

Please also check, if the disk swap has been used.
Best regards,

Fine level task subdivision is enabled. Max RAM usage was around 30-40GB out of 256GB so disk swap shouldn't have been used, but I didn't exhaustively check with powershell or Perfmon. If it would help, I can run again and try that.
