Seamless Travel crashes after a while

I’m working on a multiplayer project using GAS. In order to pass players to another level, I’d like to use ServerTravel along with CopyProperties in the PlayerState.

For some reason, after some time the project crashes, in different ways and without ever being clear about what happened in the logs.

The issue seems to be related to the Garbage Collector, because since I’ve set it to collect on every frame, the crash reproduces quicker.

So far I already thought it to be Widget related, Particle related or GAS related, because the log has appointed each and every one at different times.

The crash reporter and the IDE trace doesn’t seem to point to something specific either, so I’m getting lost.

Is there a way to actually debug this and find the source of the problem? I’d rather use Seamless Travel because it feels less restrictive.

This is one of the crashes log.
