The problem was the curve script in the unity package from SideFX. She broke the asset when taking it to the scenes, which is why it didn't work at all. There was an duplication error with filling in the dictionary, I modified the script so that old records with an erroneous key were deleted from the collection before the operation and the curve began to work. It crashed every 5 minutes, which caused me to reinitialize asset, but it was enough for me to make all the necessary assets in unity
