Odd behaviour from Workbench

I’m running workbench on Windows 10. Ever since the latest windows update, Workbench will change ( seemingly unprompted) the name of the folder ‘webuires’ located in the ‘resources’ folder to this:
“…/…/…/…/…/…/program files (x86)/tads 3/lib/…/…/…/…/…/…/program files (x86)/tads 3/lib/…/…/…/…/…/…/program files (x86)/tads 3/lib/…/…/…/…/…/…/program files (x86)/tads 3/lib/…/…/…/…/…/…/program files (x86)/tads 3/lib/webuires”
I have no idea why it does this. It seems to cause Workbench to crash after a few runs. I can manually open the .t3m in a text editor, and change the name of the folder back to ‘webuires’, after which it works fine, although Workbench changes the name back to the long …/…/… string after a few times and we go through the whole process again.
Does anyone have any idea what might cause this?
