What I’d do is double-check which partition is marked as bootable/active on the old SSD, then after cloning make sure the new SSD is configured the same. On a Windows 10/11 boot USB you can usually go into the command line & run diskpart to do those things, alternatively you do the same in Linux if you’re already using that instead.
I don’t think cloning disks would necessarily mark any partitions as bootable so that’s an extra step you may need to do.
Clonezilla typically works well enough when you’re doing the entire drive though I’ve never needed to tinker with bitlocker so can’t say if that changes things.
