Build failed for Ninja release on Windows 11 x64 for branch 6045

Describe the bug Tried to build branch 6045 with the following batch script:

set GN_DEFINES=is_official_build=true use_thin_lto=false proprietary_codecs=true ffmpeg_branding=Chrome media_use_ffmpeg=true media_use_libvpx=true rtc_use_h264=true
set GYP_MSVS_VERSION=2022
set CEF_ARCHIVE_FORMAT=tar.bz2
python3 .\automate\automate-git.py --download-dir=H:\cef-6045 --branch=6045 --minimal-distrib --force-clean --client-distrib --x64-build --with-pgo-profiles --no-debug-build --no-debug-tests --no-release-tests

To Reproduce Steps to reproduce the behavior:

Create file create.bat with above script
Created a folder named automate and created file automate/automate-git.py.
Run .\create.bat

After some hours, I received the following error:
