Unreal Engine 5.3.2 freezes when using "Convert Selection to Blueprint Class" on Datasmith-imported SolidWorks model

Thanks for your time

1.- I have simplified the assembly, I deleted like 60% of the pieces to reduce the model as much as possible, also I deleted nested assemblys by disolving them

2.- Both UE5 and Datasmith are updated and working fine per se

3.- I´ve change energy settings to high perfomance on my desk PC, there shold be no problem, my specs are:
-AMD Ryzen 7 7700X 8-Core
-32.0 GB RAM
-NVIDIA RTX 4070
-Windows 11 64 bits

It’s not like super wow, but it should be enough

My UE5 keeps freezings inmediatly as soon as i do “convert selection to bp class”

Do you thing the only solution is to use python scripting?

Output log does not show anything regarding Datasmith or the operation convert selection …

Creating actor manually is not quite the solition, as there are many pieces wich require mates so the model satisfy its purpose

thanks in advance
