Large amount of crossfades seem to result in a corrupt project file. For example, following this guide:
and working through entire song will most likely result in a corrupt project file, which crashes Cubase when trying to open the project later.
The culprit seems to be the Crossfade and/or Soft Quantize function, or both of them in combination. In other words, after applying the Delete overlaps, Close Gaps & Crossfade from Quantize Panel (Crossfade button), the project most likely ends up being corrupt, depending on the amount of crossfades applied. In my case, a generic heavy metal song with double kicks is enough. Tested with Cubase 11, and a clean vanilla install of Cubase 10.5 on a separate machine with no 3rd party software envolved. Note: the project doesn’t become corrupt if I bluntly:“All selected > Slice > Hard Quantize All > Crossfade”. Corruption seems to happen with Crossfade when Soft Quantize or manual edits are done.
Also tested by importing multiple songs with multitracked drums into a single project, and chopped and quantized them. Although the GUI becomes very sluggish, this still works, but after applying Crossfade, the project becomes corrupt. In my particular test song case, I can slice and quantize the entire song without problems. After applying Crossfade on approximately first half of the song, it still works and loads up afterwards. But if I apply Crossfade through whole song, it becomes corrupt and will not open anymore. So there seems to be some kind of ‘fixed size/magic number’ limit for Crossfade operations after which Cubase can’t handle the project anymore.
