Cloned NVMe drive unbootable using newest AOMEI Backupper

[Delly10 0]

I am in the process of finally migrating all my apps over to a newly assembled Asus ROG Strix-H pc. I've been a 20+ year user of Backupper and had to purchase their newest version over the web. My Strix motherboard has a total of 5 NVMe slots so I thought it would be easy cloning a spare NVMe just to have for emergency purposes. Clone creation completed uneventfully with no unusual displays warning me of any abnormalities. No amount of cloning will give me a spare bootable NVMe drive. I event went so far as to putting this target NVMe in it's own external enclosure and attached with my type-C USB cable without success. Been on this for almost 4 days and emails to AOMEI have yielded nothing productive hence I requested a complete refund. Per chance is anyone using Backupper and able to successfully clone spare NVMe drives? Only thing I can think of is my primary boot NVMe drive (Windows 11 Pro) has both bit locker and encryption enabled during my initial o/s build.

My new build has nothing really exotic other than the Strix motherboard, 64GB of DDR5 memory, no video card other than the built in GPU on my i7 265k CPU, and a plain jane AIO cpu cooler. Everything else works fine and this includes my HP printer, Microsoft Azure client, and Microsoft office 2010. Thanks much everyone for help or advice!
