Hi Community, back again but this time it’s very good news.
 
Basically, I’ve gone full circle and now back on (<cpu mode='custom') I’ve been running this setup for 3-4 weeks now and everything is working perfectly with zero instability across all games. When the VM is idle the resource usage almost nothing….. FINALLY a perfect VM!!!
Roblox is working via the Windows Store app as mention above, so the kids are over the moon.
 
Long story short, “Unraid Share Mode: VirtioFS Mode” was the culprit here and was causing the system to randomly lock up. Once removed all my issues were resolved and as mentioned the VM idle resources are back to near zero.
I’m glad in a way, as its forced me to learn more about the XML view by adding necessary features and pinning “emulatorpin” & “iothreadpin” which have also helped drastically with stability.
 
I have attached my XML and will now be marking this thread as resolved.

@JorgeB Thankyou for your time - I've solved this 1, Basically it was due to bad naming of the zPool.
 
I used spaces in name when formatting in Unassigned Devices, once mounted, Unraid placed underscores in place of the spaces which then lead to the issue of not being able to unmount with the error being "Cannot determine Pool Name"
 
It also stopped the system from rebooting which resulted in a hard reset (i'm guessing due to the zfs pool hanging)
 
Once I removed the spaces my next big mistake was naming the 1st dataset the same name as the zpool device, this lead to all the same issues I had before (unable to mount this time and again could not reboot, stuck on "syncing filesystem")
 
Now that I named the zpool "ZFS--BACKUP--SSD" and my dataset to "Cache-mirrored----Backup" I can mount and unmount until the cows come home!
