Project with ARA events crash

Hi everyone i recently made an edit on a project that is final mix. Client asked to add a few bars before for the new intro.
I added a signature track and used the function to add empty space between locator, the problem happened as soon i created the new space in the project. I think this is related to some audio event having spectral layers extension applied to it. The session started behaving very weird and crashing, some audio events started to disappear and so on.
I normally consolidate the events that have spectral edits or melodyne on a new track version but this one i didn’t.
Has anyone come across this issues ?
I was lucky because i did a save has before going into the new intro edit, otherwise my project would be in a very bad shape by now.
