Estimated file sizes are often a wild guess. What version of VP is being used?
Your PM link points to 43 files, but no VPJ. Post a link to it separately. It should be in the portable project folder if the project was saved.
25GB is too big to upload to a free server. Most have 15GB or lower limits. If you can isolate a small portion of the project - say 2-3 GB - that has the issue, we can test that.
SAVE PROJECT AS, and give it a unique # or name, to avoid overwriting older saves. Delete everything on the timeline but for the test section.
Then click the 'hamburger' menu at the top-left, click FILE, click SAVE PORTABLE PROJECT AS.
Note the above post, and check Properties of the portable project folder to see if its size will fit the server free space
If it's a go, upload the resulting folder. Share it (make it public), copy the shared link and paste it into a post here.
