I think this is specific to M1 Macs. I noticed the same issue reported for a similar function in a different package: https://github.com/RonRadtke/react-native-blob-util/issues/80

Hi, what @palmsey said is correct. This package isn't supporting the latest iOS version simulators on M1 Macs. But it is working fine in iOS version 13.7 simulator running on M1 Mac. I'm using iPhone 8 Plus simulator on M1 Mac and it works fine: npx react-native run-ios --simulator="iPhone 8 Plus (13.7)"

Also, I've verified the working of release version app in iPhone SE (14.1) device, iPhone 13 (15.1) device and iPhone 13 (15) browserstack (functionality worked but crashes occurred sometimes).

Specifically, I tried only this feature - await FileViewer.open(path);

Just try and it worked on iPhone 11 simulator iOS 13.7 but it will crash on iOS 15.2

Crashes now on Simulator and iOS device. iOS 15.5

i Have same issue;

Thread 66: "*** -[_NSPlaceholderData initWithBase64EncodedString:options:]: nil string argument"

Crashes in iOS 15.4 and16.0 simulator

RN: 0.65.1 macOS montenery 12.6 ( intel i9 ) xCode 14

Maybe important a point! AND MAYBE SOLUTION -->

our backend server some time return 500 error even if we send same value and parameters. when 500 error hapen; our old code save this to storage. after saving; other codes try to read it and crashing on this point. so i recomend make sure you read a readable file and setted correct value for mimeType.
