Describe the bug
When I want to use joern to parse a C# code, the following error occurs:
(my_venv)@-Pro % joern-parse /xxxxxxx/src/CommandLine/Infrastructure/
Parsing code at: /xxxxxxx/CommandLine/Infrastructure/ - language: `CSHARPSRC`
[+] Running language frontend
Invoking CPG generator in a separate process. Note that the new process will consume additional memory.
If you are importing a large codebase (and/or running into memory issues), please try the following:
1) exit joern
2) invoke the frontend: /opt/homebrew/Cellar/joern/2.0.260/libexec/csharpsrc2cpg

When I exported PDG, no files were generated
Desktop (please complete the following information):
OS：macOS 14.5
Joern Version ：HEAD+20240318-1646
Java Version：17.0.8
dotnet Version: 8.0.302
Additional context
At the same time, I have another question, why when I export PDG、AST、CPG14, there are many dot files generated in one folder, why not just one? Is there any relevant document?
