Archicad d5 livesync suddenly unreliable, causing crashes

Hey y’all,

I recently was working in live sync on a somewhat complicated file. After an ArchiCAD crash I could not get d5 live sync back up and running. I had a client meeting in just a few hours, and could not get the files to sync back. I ended up having to create a new d5 project with an ArchiCAD save file that was made before the disconnect. I figured it was a one time glitch, so whatever.

Fast forward to today. Completely different project, much more simple. I have been working on it for a month now. Went to establish live sync today and was just met with crash after crash. I can’t even establish connection with a completely blank d5 project, ArchiCAD continues to crash. I would be happy to share any files or whatever other information I need in order to fix this. All firmware is updated. I have a NVIDIA 5090, AMD Ryzen 9 9950x3D 16 Core, running on Windows 11 Pro. ArchiCAD is running in 28.3. D5 is running in 2.11.1

Hi @lakeandlandstudio
