Unfortunately, there is an annoying limitation with running these scripts in Blender currently. They must not access any context (and operators access context). I've thought about solutions for the fundamental problem of triggering operators in Blender from the outside multiple times. I did not find the time to implement any of that yet though.... That's still on my todo list.

Oh, so I guess it is the same thing at play here: #68 ?

same issue with Blender v2.83.2
but i confirm that it works well with Blender v2.80.rc
no ops issues, adding mesh causes no crash.

@JacquesLucke Did you find a solution for this yet? I have problems with all bpy.ops.mesh.xx functions it seems and maybe this is related.

Fix for bpy.context.[active_]object set to None after adding primitiv…
a064dec 
…e when run from VS Code Extension JacquesLucke#135

# Summary of issue
Calling a script via operator results in an empty context.

# Related devtalk.blender
from @JacquesLucke
https://devtalk.blender.org/t/how-to-run-a-script-from-outside-blender-script-live-link-addon/9792/3?u=jacqueslucke

# Solution
Use bpy.app.timers to register a function to run the target script.

# Changes
pythonFiles\include\blender_vscode\operators\script_runner.py
* remove the RunScriptOperator and move the contents of the execute method into a the `run_script()` function
* register a timer callback to the `run_script()` function that will execute the target script

# Potentially related issues
* When adding objects to collections the objects only show after the script ends. JacquesLucke#101
* accessing bpy.context.object crashes Blender JacquesLucke#86
* Crash when adding mesh JacquesLucke#63
* Delete is skipped JacquesLucke#68

# Testing
* execute a simple script that uses `bpy.context.active_object`
* set the #context.area:   SEQUENCE_EDITOR and run this script https://github.com/CGArtPython/blender_plus_python/blob/main/sequence_editor_frame_import/sequence_editor_frame_import_done.py
* execute the script from issue JacquesLucke#101 JacquesLucke#101
