I was able to package for windows in unreal 4.25.1 before i upgraded my windows to version 2004. After upgrading windows i started getting intel optane memory pinning error and weirdly i was also unable to package for windows in unreal. Then i followed this page https://www.intel.com/content/www/us…d-storage.html and https://downloadcenter.intel.com/dow…ane-Memory?v=t to upgrade the drivers and it fixed the unreal 4.25.1 crash on package issue.
