Embed /include dataview from other file

Thanks for your replay.
i did another try with more simple data/notes:

File: _action_1

---
type: action
dat-beg: 2022-12-20
dat-end: 2022-12-20
state: 2
---

project:: [[project_1]]

File: _action_2

---
type: action
dat-beg: 2022-12-20
dat-end: 2022-12-20
state: 1
---

project:: [[project_1]]

File: _action_8

---
type: action
dat-beg: 2022-12-01
dat-end: 2022-12-02
state: 2
---

project:: [[project_2]]

File: project_1

---
dat-beg: 2022-12-20
dat-end: 2022-12-22
type: project
state: 3
---

$=dv.span(await dv.io.load("dv_incl_ProjFile.md"))

File: project_2

---
dat-beg: 2022-12-27
dat-end: 2022-12-29
type: project
state: 1
---

$=dv.span(await dv.io.load("dv_incl_ProjFile.md"))

File: dv_incl_ProjFile

```dataview
TABLE dat-beg, dat-end
WHERE type = "action" AND project = this.file.link
SORT state ASC, dat-beg DESC  

but all I get is:
‘-’
mnvwvnm already gave me advise…
I set up a new vault only with dataview-plugin → also negative.

Obsidian Version v1.1.8,
(mnvwvnm has v1.0.3 and it works for him… )

I found this thread: Dataview: reuse DQL queries?

but I dont get through.
i tried to change the call of dv to

$=dv.view(await dv.io.load('dv_incl_file.md'))
______^^^^^^
also renamed the file to dv_incl_file.js
→ negativ
is it a bug possibly?
