Hi there! I'm sorry to hear that Filmmaker Pro is crashing after your recent update. Let's work together to resolve this issue.

To help narrow it down, can you share if you’ve tried any troubleshooting steps so far? For instance, have you restarted your iPhone, or are you able to access any other apps without issues?

In the meantime, here are some steps you can try:

1. Restart Your iPhone: Sometimes, a simple restart can help clear any temporary glitches. To do this, press and hold the power button until you see the slider to power off. Slide to turn it off and then turn it back on.

2. Check for Updates: Ensure Filmmaker Pro is up-to-date. Go to the App Store, tap on your profile at the top right, and scroll to see if there’s an update available for Filmmaker Pro.

3. Reinstall the App: If the app continues to crash, deleting it and then reinstalling can resolve issues caused by a faulty update. To delete, press and hold the app icon until the "Remove App" option appears, tap on it, and confirm. Then, go to the App Store to download it again.

4. Free Up Space: Ensure you have enough storage on your device. Go to Settings > General > iPhone Storage to check. If your device is low on space, try deleting some unused apps or files.

5. Reset Settings: If the above steps do not work, you can try resetting all settings. This won’t delete your data but may resolve underlying conflicts. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.

Please let me know if any of these steps help or if you’ve already tried some of them. If the problem persists, we can look at more advanced troubleshooting options.
