Macrium is listing three drives of the exact same model though with different serial numbers. Is that correct? Just seems odd that you got the exact same model after however long you've had the original and I just want to confirm that.
Your C drive is on an MBR disk (Disk 1 MBR). So there was no Microsoft Reserved Partition which is what I thought you were referring to. The System Reserved partition is actually where Windows stores the initial boot files (the boot loader, the BCD file, etc.) when using an MBR disk. I don't think Macrium Reflect "moved" the partition (it has no such function). I think it's more likely that partition became so corrupted during the clone that it's unreadable on the original SSD, and that this also affected the size that Reflect made the partition on the new drive, and caused the cloning process to end prematurely. (Either that or you didn't select all the partitions to be copied.)
I'm not even sure how your computer managed to reboot, if you have actually done so since that partition disappeared. If you haven't, don't try, because it probably won't start.
If you can download a portable app that reads SMART data, it would be interesting to see what it says about the old drive. (You want to avoid actually installing anything on it at this point, to reduce the usage.) You could get Crystal DiskInfo in portable format or GSmartControl which is already portable, using the laptop, and put it on a flash drive.

First I will point that every moment that you continue using the old drive you are increasing the risk that you're going to lose more data. Since you've been struggling with this for some time I strongly suggest you give up on trying to clone this, and simply do a fresh install of Windows on the new drive, then manually copy files from the old one or restore them from whatever other backup you are using, if any. Yes, you'll have to go through the pain of reinstalling and reconfiguring applications, but at least you won't blow away all your data files.
The first thing I'd do is make backups of your data files and any configuration files on the C drive that you might not be able to recover from any other location if the old SSD just dies suddenly. It looks like you have 100GB of free space on the G drive you could use. If you've got all your things like Documents, Pictures, etc. being synced to OneDrive or something else then those are fine, and you just need to make copies of anything that isn't syncing to the cloud. If your other apps like browsers are syncing to cloud accounts then you're pretty much set there, but if not, then you'd want to make backups of them.
It would be a good idea to download a Windows 10 ISO from Microsoft using the laptop, in case you need to put it on a flash drive for recovery on the dying computer or decide to do a fresh install.
Below is what I think ought to work, assuming Reflect has any chance of copying those partitions. Note that even if it succeeds, there is a chance that you will be copying corrupted files which may include either operating system files or your application or data files. Cloning a partition also copies any "bad sector" data that the filesystem recorded. These are additional reasons to just do a fresh install.
Right now you don't know if that System Reserved partition is any good, since it may have cloned bad data. But, you can use Disk Management to just shrink it back down to say 50MB (1MB less than it was on the original drive simply for leeway). Then Reflect can attempt to clone it back to the original drive. Hopefully the old drive can write the data and will reallocate blocks to prevent writing to bad ones, but no guarantee. This drive seems very far gone, so this is still risky, but if it works, then your system will be able to start up if it reboots assuming the data being cloned wasn't corrupted. (If DM won't let you shrink it, I'll advise what to do.)
After that, you can try cloning the C drive and the additional partition. That's the Windows Recovery Environment; if it fails to clone that's not a problem as you can recreate it. The System Reserved partition can also be recreated, but if it cloned with bad data then I'd assume other OS files are bad as well and simply say you need to do a fresh install.
