DEFINITION QUERY NOT WORKING

[WeronikaBąkowska]

Hello, i have weird problem
this is my code

import arcpy

aprx = arcpy.mp.ArcGISProject("CURRENT")

maps = aprx.listMaps("Layers4")

if maps:
m = maps[0]

for lyr in m.listLayers("Land Boundary"):
if lyr.supports("DEFINITIONQUERY"):
lyr.definitionQuery = "Flurstueck = 1237"

and it creates Definition query in my layer properly 

sadly it doesnt work on itself and i have to manually click apply otherwise map disappears and is white.
I assume its bug, please help

additional info:
even tho definition query is created, i get info

ArcGis Pro versions that i tired with 3.0.2 and 3.4

Additionally if i tried to deactivate the query right after its created to try to switch it on again and hoping it would solve problem, but after adding this line to code
lyr.updateDefinitionQueries(
[{'name': 'Query 1',
'isActive': False}])

program simply crushes and closes 😞
