Yesterday my project was perfectly fine, worked as usual without any particular bugs. Today I opened my project and started by a little play-test without changing anything (so my project is EXACTLY the same as yesterday), I entered play-mode, detached from the player character to navigate in the scene as a spectator and as soon as I clicked on a blueprint actor the whole engine froze and after about 5 minutes my laptop restarted closing every active program an leaving without a crash report.
I thought it was just a punctual crash so I restarted the project and tried to do the same manipulation to make sure that it wasn’t gonna happen again, turns out (after a whole day of crash test) EVERY TIME I enter play-mode, detach from the player character and select a blueprint actor (whether by clicking on it or just selecting it in the outliner) the whole engine freeze and if I’m lucky it crashes with a crash report telling me absolutely nothing. It seems like during the crashes Unreal Engine consume A LOT of memory, approximately 10Go that takes up to 95% of my Memory whereas usually it doesn’t exceed 4Go. The bug happens only if I select a blueprint actor, a static mesh for example doesn’t cause any problem, but a blueprint actor composed of several static meshes and no logic causes the bug too.
I tried the same manipulation in another smaller project and while it slows down the engine during a second or two it doesn’t provoke a crash.
I honestly don’t know what I should do, as I said I didn’t change a single thing in the project between the time it worked without a problem and the crashes. So if someone has already encountered something like that or has a suggestion of what could be the cause or what should I do, thanks in advance !
