Vectorworks is crashing all the time and is very slow

Hi, Vectorworks is crashing all the time and is very slow. At school they forbidden us to upgrade to version 2025. What can I do to solve this?

Version of the app: Vectorworks 2024

Windows 11 

Microsoft 365

Basic steps to reproduce the problem: Vectorworks is crashing and is very slow

Expected result: that Vectorworks is not crashing anymore and I can work with normal performance within that program

Very important; because I have an examen on it next Tuesday

Can you help me to resolve this, please?

Thanks in advance,

Ruhne Nys
