If I've tried everything else, are there alternative video editors I can use to edit my CapCut project?

Yes, there are many alternative video editors. Some popular options include DaVinci Resolve (free and paid versions), Adobe Premiere Pro (paid subscription), Filmora (paid), and OpenShot (free and open-source). While you can't directly open a CapCut project in these editors, you can export individual video and audio clips from CapCut and reassemble them in a different editor. Consider the learning curve and features when choosing an alternative.
