[Bug][python] This error "Not found: importCode" exists both on joern build 4.0.408 and build 4.0.423

[refergit]

Describe the bug
I just noticed a relevant issue. I am also using Joern server but found Joern server did not work both on joern build 4.0.408 and build 4.0.423 (v4.0.342 worked).
I found that the version of scalaReplPP is 0.5.3 in joern 4.0.342 and 0.6.1 from joern 4.0.408.

-- [E006] Not Found Error: -----------------------------------------------------
1 |importCode("D:\package\device\sta\")
|^^^^^^^^^^
|Not found: importCode

To Reproduce
Steps to reproduce the behavior:
cat run-joern.py

from cpgqls_client import CPGQLSClient, import_code_query, workspace_query

server_endpoint = "localhost:8080"
client = CPGQLSClient(server_endpoint)

query = import_code_query("D:\package\device\sta\", "test-app")
result = client.execute(query)
print(result['stdout'])

Expected behavior
importCode can work well as previous.

Hmm, on linux this works fine...
Will try to reproduce on my windows VM.

I cannot reproduce on windows either (with a locally staged version of master, i.e. sbt stage)
How exactly did you get and start joern?
