SOLVED Crash when changing Share Type on pool from Illumos/Nexenta

[GiveupI]

Hi there, Freenas newbie here !

Being fed up of Nexenta and their policy, I decided to try, and hopefully switch to FreeNAS.
Unfortunately, it doesn't work very well this far...

I imported my pool, that worked without issue.
So what I have is :
Tank (My imported pool)
- Dataset "Data"
- Dataset "Backup"
- Dataset "DatastoreNFS"

I checked the settings on the datasets to be sure everything was a OK, and noticed that they all were set up as Unix share type.
As "Data" and "Backup" are being used by Windows and macOS clients over SMB shares, I have to switch them to Wndows share type.
I tried to switch "Data", and when clicking save, Freenas immediately encountered a fatal error, and rebooted.
I then tried with "Backup", it worked. Tried again some more times with "Data", error and reboot again.

Here is what I get :

Could someone help me please ?

Edit :
OS Version : FreeNAS-11.2-U3
I added the debug file, in case it helps.

Please create a report at redmine.ixsystems.com that includes that debug so a dev can investigate.

Thanks.
I just created it, bug #85107
Let me know if you need more information, I think everything should be in the debug file ?
