Failed to change the status of an order

[Solucionesvigo]

With Joomla 3.9.21 , PHP  7.2.32 and with virtuemart version 3.8.4 10335 I get an error when trying to change the status of some orders.

I think the problem only arises in orders that have a status created by us. (I'll text it more)

We look for what may be the cause and it is the file administrator / components / com_virtuemart / models / orderstatus.php

Forgive for my english, translated by google

Appears to be language error? 

Object of class stdClass could not be converted to string in /www/Clientes/superoliva/web/libraries/src/Language/Language.php

Si pero en la version 9831 no falla.
Acabo de hacer un mirror de svn de virtuemart en github , donde hizo una rama para que veas la diferencias.

Yes, but in version 9831 it does not fail.
I just mirrored virtuemart's svn on github, where it made a branch for you to see the differences.
