USMT scanstate.exe getting stuck on one file across several computers

Question

I've been working on migrating a couple computers with USMT, and on both of them the tool has been getting stuck on C:\Program Files\windows nt\tabletextservice\en-US\TableTextService.dll.mui. The computers are two completely different people in completely different job roles. It gets completely stuck on this file - it'll sit for hours and hours before moving on. The file itself is only 9kb. At some point it moves on, but the last time I tried it took over 18 hours.

The command I'm using is: scanstate.exe \\REMOTE-SERVER-LOCATION /o /vsc /localonly /c /efs:copyraw /v:5 /l:C:\Windows\CCM\Logs\scanstate.log /progress:C:\Windows\CCM\Logs\scanstateprogress.log /i:Custom_NoSVN.xml /i:MigApp.xml /i:MigDocs.xml /ue:%computername%\* /nocompress. The last few lines of the log file are nothing interesting.

Both machines are on Windows 10 using scanstate.exe Version 10.0.10240.16384

I'm at a loss here. I thought that it might've been the last file before it moved onto another big folder, but there's still multiple folders alphabetically after windows nt that have other tiny files, so it doesn't seem to be that.
