This report is missing:

Last version that worked.
Exact steps to redo the error.
A blend file (unless there are simple steps to redo this from the default startup).

Last version that work: unknown
Exact steps to reproduce : see crash log
Blend file: not necessary (see 5 steps from crash log and perform on the default cube)

In case reading the crash log is not acceptable:

Cube
Edit mode
Select 3 verts
New transform from selection
Object mode
Turn on affect origins only
Object menu /transform/ Align to transition orientation.

Cannot reproduce either 7b988188dc nor f09fcda8b6.

Crash logs seems to be a bit different from the written down repro steps?
Here is one file with the crash log (reproducable in an operator):
#81074.blend

Open file
execute script
with mouse over 3DView: {key F3} > Simple Operator > execute > no crash

Here is the file with the repro steps (except last)
T81074_repro_steps_except_last.blend

Open file
Object menu > Transform > Align to Transform Orientation > no crash

@3di : What could I be doing wrong?

@lichtwerk , I've automated the exact steps to make it a bit faster to test. Sometimes it doesn't happen on the first iteration, I was able to reproduce without the below also.

class SET_OriginsToSelected(bpy.types.Operator):
    bl_idname = "obj.set_origins_of_selected_objects_to_selected_faces"
    bl_label = "origins to selected faces"
    bl_options = {'REGISTER','UNDO'}

    
    

    def execute(self, context):
        

        os.system('cls')

            #STORE SELECTION
        original_selection = bpy.context.selected_objects

        #deslect everything
        bpy.ops.object.select_all(action='DESELECT')


        #set to use origins only
        bpy.context.scene.tool_settings.use_transform_data_origin = True

        

        for obj in original_selection:
            print(obj.name)
            
            
            
            try:

                bpy.ops.object.mode_set(mode='OBJECT')
                obj.select_set(True)
                bpy.context.view_layer.objects.active = obj
                bpy.ops.object.origin_set(type='ORIGIN_CENTER_OF_MASS', center='BOUNDS')


                bpy.ops.object.mode_set(mode='EDIT')
                bpy.ops.transform.create_orientation(use=True)
                bpy.ops.object.editmode_toggle()
                

                bpy.ops.transform.transform(mode='ALIGN')
                bpy.ops.transform.delete_orientation()
                obj.select_set(False)
                
            except Exception as e:
                print(e)

        bpy.context.scene.tool_settings.use_transform_data_origin = False
        
        

        #reselect objects
        for obj in original_selection:
            obj.select_set(True)
     
        return {'FINISHED'}

Hm, still no crash here:

It can take a few goes.

maybe put it in an additional loop to trigger the error more quickly without manually running it over and over.

also try selecting 3 vertices or 2 edges instead of a face.

Hm, still cannot reproduce.
At this point, all I can suggest is trying to put together a file with script that can trigger it reliably on your side, dont know what else I could do here, sorry.
