Myparcel error on orders management

-- HikaShop version -- : 4.7.1
-- Joomla version -- : 4.3.0
-- PHP version -- : 8.0

Hi, in hikashop -> orders i get this message:
An error has occurred.
0 Attempt to assign property "my_parcel" on bool

all other hikashop functions seem to keep workling.

Any idea what went wrong?
The only change i made recently is PW Google Tag Manager plugin which doesn't seem related. (disabling has no result)

Thanks, Nico

Maybe important to know:

Order page was in a search.
Disabled the myparcel plugins, order page shows, deleted the search, enabled myparcel plugins, order page shows again.
So this error is search inside orders related.
