   Summary to solve re-occurring Epic Privacy Browser launch issues   
      
   Recurring Problem:   
   Epic Privacy Browser will suddenly, inexplicably, simply fail to launch   
   (wouldn't start from existing shortcut, not running in Task Manager/Process   
   Explorer, no error messages and a reboot doesn't help but a re-install always   
   fixes the recurring problem    
   which happens sporadically, about once every few months).   
      
   Successful Solution (20250615):   
   I deleted the %localappdata%\Epic Privacy Browser\User Data\Default folder.   
   Result: Epic launched successfully from the shortcut that previously stopped   
   working.   
      
   This happens about once every few months.   
   I don't know why.   
      
   The assumption is "something" got corrupted.   
   But what?   
      
   Lessons Learned / Recommended Targeted Approach for Next Time:   
      
   Before deleting anything, ALWAYS BACK UP:   
    a. %localappdata%\Epic Privacy Browser\User Data\Default\Bookmarks (Your   
   saved bookmarks)   
    b. %localappdata%\Epic Privacy Browser\User Data\Default\Login Data (Saved   
   passwords)   
    c. %localappdata%\Epic Privacy Browser\User Data\Default\Preferences (Core   
   browser settings)   
       Note: These are files within the Default folder, copy them before deleting   
   Default or specific sub-elements.   
       Copy them back later after restarting & immediately killing Epic, which   
   re-creates the Default folder.   
      
   Once you've copied those files, then you can attempt a targeted deletion of   
   suspected corrupted elements (one by one, testing launch after each deletion),   
   attempting to restart Epic after each targeted deletion.   
      
   Most likely culprits (in order of likelihood):   
   1. Delete the file containing Epic's core configuration. Then test.   
      %localappdata%\Epic Privacy Browser\User Data\Default\Local State   
      
   2. Delete the folder containing session data for open tabs/windows. Then test.   
      %localappdata%\Epic Privacy Browser\User Data\Default\Session Storage   
      
   3. Delete the session data folder, often alongside Session Storage. Then test.   
      %localappdata%\Epic Privacy Browser\User Data\Default\Sessions   
      
   If those don't work, then try these far-less-likely possibilities:   
   A. Delete the folder for web content cache. Then test.   
      %localappdata%\Epic Privacy Browser\User Data\Default\Cache   
      
   B. Delete the folder for compiled JavaScript. Then test.   
      %localappdata%\Epic Privacy Browser\User Data\Default\Code Cache   
      
   C. Delete the folder for extension data. Then test.   
      Note: This will likely require re-enabling/re-logging into extensions.   
      %localappdata%\Epic Privacy Browser\User Data\Default\Extensions   
      
   D. Delete the folder for offline web app data. Then test.   
      %localappdata%\Epic Privacy Browser\User Data\Default\IndexedDB   
      
   If targeted deletions fail, delete the entire Default folder.   
   Then restore backed-up data. This always works.   
      
   If you know of a better solution, please let the team know as we're all more   
   powerful together than we are all alone.
