Mendix Studio Pro 9.18.0 regularly freezes

I have been using Studio Pro 9.18.0 for a few days now. I like the improvements Mendix made, but multiple times a day Studio Pro freezes completely. Nothing helps, i need to kill Studio Pro and restart.   Anyone else having this issue?   I have a feeling it is related to using ctrl-S or ctrl-shift-S for saving changes.

Hi Michiel, 


I experienced a issue similar to the related onto the Mx 9.18.2 fix →

  • We fixed the issue where Studio Pro froze when microflow activities were dragged from the toolbar. (Tickets 168530, 168328, 165904, 165769, 165516, 165491, 164808)


In My case, The error started after a Windows 11 cumulative .NET update…



Probably the froze issue is related to .NET vs Mendix… 


Because,  after uninstall kb5017271 freezes errors disappeared.  

( and later on the KB5020622 for Windows 11, version 22H2, seems to fixed something as well)




I use to have a lot of trouble with Mendix freezing, until I start working with branches, that solved the problem. 

if your not the only one working on the same development branch I gets super slow. I suggest you to create your own one. if you need help with this please comment and I can guide you.


Hope you find the solution !
