Blueprint compiling error with arrays. Project wont start

Hi,
im working on a blueprint-project where, on construction, i create spring arms, put them into an array and attach meshes to them to deal with rotation around axis. first i fill arrays with same amount of spring arms and afterwards i resize arrays to match size to added spring arms.

it worked fine, i could see apring arms in variable in editor, but when i clicked on play array was empty and contained zero objects. so i thought it would be good to change order: first resize array, then fill array with spring arms, so logically it would have to work. but when i clicked on compile game crashed and now i cant even start project anymore. whats going on?!?! please help me.

thx in advance.
here error message from editor:

Hi tuffzinator,

Does this occur in a clean project with no additional content? Additionally, can you post a screenshot of your blueprint in question?

It’s not a clean project. I worked on it for about 2-3 months but mostly with stuff which came with engine. I imported 2-5 textures. Don’t know what you consider clean. If clean means empty then no. If clean means only starter content then mostly yes.
I was able to open a backup version of my project so it’s all good now. But maybe I helped you debugging engine with my problem.

Hi tuffzinator,

What did you do with these textures after importing them, or did engine stop working immediately after importing?

Hi tuffzinator,

We have not heard from you in quite some time. I am marking this as answered for tracking purposes. If you are still experiencing this error, please respond with requested information.
