Summary
UEFN reports “Total project size is 293,634 MiB larger than allowed (maximum is 2 GiB)” when attempting to stage/upload the project, despite all local verification showing the actual project size is nowhere near this figure.

Steps to Reproduce
Open project “Myproject” (currently at v407, last successfully uploaded 30/07/2026)
Click Launch Session / attempt to upload
Staging fails with: “Failed to stage project for upload. Total project size is 293,634 MiB larger than allowed (maximum is 2 GiB).”
Expected Result
The project should stage and upload successfully, or at minimum show an accurate project size. Given the local Content folder is only ~3 GB and the in-editor Project Size tool shows Upload Size as 810 MB / 2048 MB (well under the limit), staging should complete normally.
Observed Result
Staging fails with: “Failed to stage project for upload. Total project size is 293,635 MiB larger than allowed (maximum is 2 GiB).”
This does not match any local measurement:
- Content folder on disk: 2.99 GB (4,369 files)
- Local .urc cache: 3.22 GB (63,927 files)
- In-editor Project Size tool: Upload Size = 810.205 MB / 2048 MB
- Staging log (LogValkyrieModuleStagingContext): “Loose files total 2454846866 bytes” (~2.34 GB), 1316 loose files
The project is currently at v407 (last successful upload 30/07/2026). I suspect the size calculation may be incorrectly including cumulative server-side revision control history rather than just the current content diff, since no local file/folder can account for a 293,635 MiB (~287 GB) overage.
I already tried renaming the local .urc cache to force a clean resync — no change to the error.

Additional Notes
This appears to be a server-side calculation issue rather than an actual local file size problem, since all local measurements (Content folder, .urc cache, in-editor Project Size tool, staging logs) are consistent and small. Happy to provide the full log file if needed.
