Patch [ACSD-50814]: can't be applied

Error: patch ACSD-50814 can't be applied
Magento 2 Community Edition, version 2.4.6.0-patch3
Applying patch ACSD-50814 (/home/XXX/public_html/vendor/magento/ quality-patches/src/../patches/os/ACSD-50814_2.4.6.patch) failed.
error: app/code/Magento/Sales/Model/Order/Creditmemo/Total/Tax.php: No such file or directory

Why does this patch applies to a file in app/code ?

Thanks
