Hi Michiel,
I experienced a issue similar to the related onto the Mx 9.18.2 fix → https://docs.mendix.com/releasenotes/studio-pro/9.18/#fixes
In My case, The error started after a Windows 11 cumulative .NET update…
(https://support.microsoft.com/en-gb/topic/october-11-2022-kb5017271-cumulative-update-for-net-framework-3-5-and-4-8-1-for-windows-11-version-22h2-535ac8db-c89b-43f7-abd7-a3c3240320e6)
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)
Att
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 !
