There are large numbers of people reporting crashes when uploading their island! SERIOUS

Summary

Too many people are reporting fatal crashes regarding their private islands attempting to be uploaded, and memory calculations failing. There have been many posts on here regarding this, and with no answers.
I have worked on my game for hours daily expecting myself to publish weeks ago, but I am hit with crashes every time I hit Upload Private Island OR Launch Memory Calculation.
Like many others, I have 0 problems uploading and launching memory calculations with other, older projects. For some reason, it’s with my recently worked on project that refuses to perform those actions.
I very much would appreciate if this was problem to be taken with High Priority with Epic, because I think there are a lot of us who are unable to publish our games because of this, and it seems to date back to early November for others?

Additional Notes

(The only assets that I got that are imported are Materials. No custom props, just custom materials. I’ve kept my memory below 100k.)
(The weirdest part is sometimes my private island WILL upload even when it crashed before finishing, but I can’t launch a memory calculation even then. Crashes as usual)
