I managed to fix this error. Basically, here’s what I did: I had CapCut version 5.3.0.1964 installed, and from there I updated it to the latest version (DO NOT DOWNLOAD IT FROM THE WEBSITE, UPDATE IT THROUGH CAPCUT ITSELF).
Once it’s updated, open it, create any project, and go through each tab so it loads all the filters. After that, open the CapCut file location—you’ll see two versions there, the old one and the updated one. Uninstall the old one directly from that folder and then reinstall it.
DO YOUR PROJECT WHILE LOGGED OUT. Once you finish, log in, run the .exe, and extract it.
Copy the folder with the name of the current version, and after installing the old version, paste both together. BY DOING THIS, you’ll kind of bypass the internet error — I’m still testing it!
