The previous fix (setting sslBackend in pre_build_script.sh) only applied to nested tokenizer submodules. The top-level submodule checkout still used schannel via the reusable workflow's `submodules: true`, causing SEC_E_ILLEGAL_MESSAGE errors when cloning from git.gitlab.arm.com. Move all submodule initialization into the pre-build script where we can control the SSL backend, and disable submodule checkout in the workflow.
Move submodule initialization above the aarch64 sed workaround so the file it edits is guaranteed to exist even if the caller disables submodule checkout. Also remove the redundant UNAME_S assignment later in the script.
The default 60-minute timeout from pytorch/test-infra is too tight for the Windows wheel build + smoke test, causing jobs to be cancelled.
…ution pthreadpool's condvar-based synchronization on Windows can deadlock with multiple threads due to a lost-wakeup bug in signal_num_recruited_threads. Reset the threadpool to 1 thread before loading the model to avoid the issue.

There was a problem hiding this comment.
if you set this to (2) does it still hang? Just curious
