Instant Crash when using splines in 4.26.1

Hello,
I am using UNREAL 4.26.1 version and I am having a peculiar problem

In landscape mode, I add an extra layer to my landscape and reserve it for splines, then I add spline points.
Once I try to click on a spline point in order to edit its shape, UNREAL crashes instantly. And the crashing is constant and standard, once I do that I get a CTD each time.

Does anyone else experience a similar problem, is there a workaround or a solution?

Thanks in advance.

What does your crash report say?

I am having the same issue. Adding the spline is okay but trying to edit the segments crashes 4.26.1

Noticed the same problem today. UE 4.26.1. / Windows 10.

My landscape was in a sub level, as was the spline I tried to create. Hard crash every time I tried to pick a spline point.

After recreating the landscape in the persistent level, the error hasn’t returned (so far).

I get this exact same issue. I try to edit the landscape spline and ue4 crashes as soon as I try to edit the vector.

Yeah it definitely has issues, especially if you copy and paste nodes. I had to go back to v4.23 because it seemed to be the most stable for me.
