Just see the list in https://ci.libreoffice.org/job/gerrit_windows/

And https://gerrit.libreoffice.org/75463 was force-pushed after an Abort.

I know there are still problems with the Scheduler code on Windows, eventually
the AnyInput handling. Probably it's the same then
https://bugs.documentfoundation.org/show_bug.cgi?id=123583
My guess is LO is generating system events, so processing is always interrupted.

Also see https://gerrit.libreoffice.org/#/c/75568/

I can help debugging the general problem, but since I don't have Windows or a
Windows build, I can't do it myself.
