Finally, it seems to be that:

[Unhandled Exception: EXCEPTION\_ACCESS\_VIOLATION writing address 0x00007fff1d087718](https://forums.unrealengine.com/t/unhandled-exception-exception-access-violation-writing-address-0x00007fff1d087718/674766)

But it only works when I do not solve the unknown structure problem, once I solve it, refreshing the node I keep getting this error.
