If you are the developer, make sure to deploy a minified Shipping build and consider migrating to WebAssembly for optimized memory usage.

im getting this error on all unreal engine 4 versions , tried blank project and tried everything nothing is working. shipping build, development build nothing is working.

this happend after i added web browser built in plugin even tho i removed it but still showed the error and each time i test a new project the same error appears.

please help!
