try this, please see the following :
step

1. npm install @babel/plugin-transform-react-jsx or yarn add @babel/plugin-transform-react-jsx

2. go to config-overrides.js : Then add the package installed to plugins...
   please see below,

const fs = require('fs');
const path = require('path');
const webpack = require('webpack');

const appDirectory = fs.realpathSync(process.cwd());
const resolveApp = (relativePath) => path.resolve(appDirectory, relativePath);

// our packages that will now be included in the CRA build step
const appIncludes = [
resolveApp('src'),
resolveApp('../common/src'),
resolveApp('../../node_modules/@react-navigation'),
resolveApp('../../node_modules/react-navigation'),
resolveApp('../../node_modules/react-native-gesture-handler'),
resolveApp('../../node_modules/react-native-screens'),
];

module.exports = function override(config, env){
config.module.rules.push({
test : /.(js|mjs|tsx|ts)$/,
exclude : /@babel(?:\/|\{1,2})runtime/,
use : {
loader : 'babel-loader',
options : {
babelrc : false,
configFile : false,
compact : false,
// The configration for compilation
presets : [
[
'module:metro-react-native-babel-preset',
], // Add this line,
[
require.resolve('babel-preset-react-app/dependencies'),
{ helpers: true },
],
],
cacheDirectory : true,
plugins : [
'@babel/plugin-proposal-class-properties',
'@babel/plugin-proposal-object-rest-spread',
'@babel/plugin-transform-flow-strip-types',
'@babel/plugin-transform-react-jsx'
[
'module-resolver',
{
alias : {
'^react-native$' : 'react-native-web',
},
},
],
],
},
},
});
return config;
};

thanks

paste it to *config-overrides.js

This JS is not valid (check module-resolver)
