Exact steps for others to reproduce the error

  • move your mouse over to the Properties Editor
  • hit F3 for search

Hi @Andrej730 , you don't have a modal() call inside your delay operator, so returning {"RUNNING_MODAL"} can lead to unexpected behaviour.

Try:

    def modal(self, context, event):
        return {"FINISHED"}
    
    def invoke(self, context, event):
        context.window_manager.modal_handler_add(self)
        return {"RUNNING_MODAL"}

@ChengduLittleA tested, same error in console with code below:

import bpy
import time

class DelayOperator(bpy.types.Operator):
    bl_idname = "object.delay_operator"
    bl_label = "Delay Operator"
    bl_options = {"REGISTER", "UNDO"}

    def invoke(self, context, event):
        return {"RUNNING_MODAL"}

    def modal(self, context, event):
        return {"FINISHED"}

    def execute(self, context):
        return {'FINISHED'}

def register():
    bpy.utils.register_class(DelayOperator)

def unregister():
    bpy.utils.unregister_class(DelayOperator)

if __name__ == "__main__":
    register()

@Andrej730 note the context.window_manager.modal_handler_add(self)

@Andrej730 note the `context.window_manager.modal_handler_add(self)`

I suspect that you probably messed up some internal registrations because edit_geometry_nodes_modifier_poll(context) isn't anywhere near your code. Try restarting blender, remove your own script files, or factory reset and see, here I'm not able to get that error even if I run your original script directly.

Just tested again by downloading another portable 3.5.1 and running it with blender --factory-startup.
Also tried on friend's PC, same error.

Can confirm (this has nothing to do with your script though, can be reproduced with other steps as well), will check a bit then come back with my findings.

So this happened in the Properties Editor, but actually pulling up F3 search there regardless of having run any script prior.

Can be reproduced just like this:
from the default startup file:

  • move your mouse over to the Properties Editor
  • hit F3 for search

See the PR that fixes this for more information

Will raise prio since this is technically a regression
