react native svg error child.isClassAccessorProperty is not a function on upgrading react native from 68.1 to 70.6

Thanks in advance
I received the below error when I tried to upgrade react native from 68.1 to 70.6.
I tried this in android.
I ran react-native run-android and everything went well.
Upon running the app the metro bundler started loading 99% and showed this error in red screen

Once again thank you.

Updating the package.json file helped me to resolve this.
just downgrade the babel versions like below
Also make sure same below version are in package-lock.json file
"#babel/core": "7.12.9",
"#babel/runtime": "7.12.5"

To solve this issue, you need to delete the "node_modules" folder and run either
"yarn install" or
"npm install" command.
It is likely that you switched to a Git branch with a higher version of Babel, which is causing the problem.

Unable to apply changes on device: DEVICE####. Error is: Cannot read property 'env' of undefined

I get this issue after my first android build; then, before that, the project run in development in the device and even in an emulator. Also the error happens in the emulator too.
I has been researching about that. Update to the current last versions of NativeScript tns-android: 5.4.0 tns-core-modules: 5.4.3 nativescript-vue: 2.2.2, also update the firebase plugin nativescript-plugin-firebase: 9.0.1. And this doesn’t allows me to continue the project. I am so frustrated in this moment about this issue.

Thanks in advance for any help, this has totally block the development of the project.

this error is expected if you are trying to use nativescript-dev-webpack#next with latest official version of NativeScript CLI (5.4.2) as they are not compatible with one another (preparing for NativeScript 6.0 release).
If you would like to use nativescript-dev-webpack#next you will need to install nativescript#next as well.
Hope this helps!

The development server returned response error code :500

I have just created a React Native application in Webstorm , but when i run it, it shows this error :
The development server returned response error code: 500

Why ?
Below is the image :

This is what i did in the command prompt It helped me.
npm uninstall babel-preset-react-native
npm install babel-preset-react-native#2.1.0
It means the new version of babel-preset-react-native library and there is an unsupported trailing commas on that new version.

I had this problem. It resolved by correcting the code. Take a look at the node window that has opened when you ran "react-native run-android", It's reporting where's the problem, for example it reports:
Unexpected token (27:6)
and then it reports a part of your code that is making the error. Open up the App.js file, review the code part that has made the problem and correct it.
Take a look at the below picture and pay attention to the yellow part.

I managed to solve the issue. To anyone else who encounters the issue, re-installing watchman did the trick for me:
brew uninstall watchman
brew install watchman
My app is now running

Also, I tried the Wathman install/uninstall route, with not much luck. What did work was making sure I updated and changed the version of node as used by nvm.
e.g. nvm install 4.1.1
