REMINDER: Always make sure you upgrade Explorer Patcher after installing Windows updates. Today my father called me because his laptop was stuck in a File Explorer crashing loop. I killed (End Task) File Explorer process from Task Manager and then loaded (New Task) Microsoft Edge (MSEDGE) so I could download latest Explorer Patcher version and install it. Once I installed latest version File Explorer worked properly and my father could finally use his laptop.
So if you encounter a File Explorer crashing loop, the solution is to install latest Explorer Patcher. Even if it is the same version, it might be corrupt (unsuccessful upgrade) and cause issues. Just download it again and reinstall to repair.
