Hey Pedro, sorry to hear that. Yes, I can imagine it being very frustrating. My business model is basically reliable on image/video uploads as well.
The only thing that worked for me was painfully going into the Upload provider code and modify it like I mentioned in the above comments (essentially replacing fs.readFile() with fs.createReadStream() which seemed to have solved the issue for now. It was quite a hassle to fix and took a few days but that was mainly due to my lack of node experience. I wish you all the best!
