after creating a folder to save recorded videos and I change the theme of the app, it prompts me to input the name of the folder

Expected behavior

I expected that when I created a folder to save recorded videos and I changed the theme of the app, it'll change without any hassle.

Actual behavior

After creating a folder and changing the theme, I'm prompted to rename a folder I just created and clicking OK crashes the app.

How to reproduce

• launch the screen cam app

• navigate to save location

• click the plus icon on the top right to create a new folder

• after creating a new folder change the theme of the app to any theme you decide

• there will be a prompt of naming the new folder you previously created and click ok crashes the app

• device: HTC M7
• Operating system: android 6.0.1
• software version: v1.8.5
