Blender: Run Script - Exception Access Violation error

[jonmatthis]

This appears to be the same error in the Closed Issue #40

Blender version 2.93.0Alpha running on Windows 10

Blender Start outputs:

Running a simple script to create a Suzanne head with Blender: Run Script works fine:

import bpy

bpy.ops.mesh.primitive_monkey_add(size=2, enter_editmode=False, align='WORLD', location=(0, 0, 0), scale=(1, 1, 1))
print(0)

and produces the following output:

Got GET: {'type': 'ping'}
127.0.0.1 - - [19/Mar/2021 13:12:59] "GET / HTTP/1.1" 200 -

However, a script that tries to create a SECOND suzanne head fails after creating the first one.

That is, this script:

import bpy

bpy.ops.mesh.primitive_monkey_add(size=2, enter_editmode=False, align='WORLD', location=(0, 0, 0), scale=(1, 1, 1))
print(0)
bpy.ops.mesh.primitive_monkey_add(size=2, enter_editmode=False, align='WORLD', location=(0, 0, 0), scale=(1, 1, 1))
print(1)

produces this output:

Got GET: {'type': 'ping'}

Thank you so much for the Add-On! Please let me know if there is anything else that I can do to help!

I got similar issue. Is this more related to the PTVSD being replaced by debugpy in VS Code? Or perhaps just I am not using Blender in Admin mode?
