}

then i solved it by setting environment variable like this

$env:NODE_OPTIONS="--openssl-legacy-provider"

then i use

npm start

i get

ERROR in ./node_modules/ws/lib/websocket.js 11:21-38
Module not found: Error: Can't resolve 'stream' in 'D:\projects\MKV web\node_modules\ws\lib'
Did you mean './stream'?
Requests that should resolve in the current directory need to start with './'.
Requests that start with a name are treated as module requests and resolve within module directories (node_modules).
If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too.

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
        - add a fallback 'resolve.fallback: { "stream": require.resolve("stream-browserify") }'
        - install 'stream-browserify'
If you don't want to include a polyfill, you can use an empty module like this:

ERROR in ./src/worker/ffmpeg-core/ffmpeg-core.wasm 1:0
Module parse failed: Unexpected character '' (1:0)
The module seem to be a WebAssembly module, but module is not flagged as WebAssembly module for webpack.
BREAKING CHANGE: Since webpack 5 WebAssembly is not enabled by default and flagged as experimental feature.
You need to enable one of the WebAssembly experiments via 'experiments.asyncWebAssembly: true' (based on async modules) or 'experiments.syncWebAssembly: true' (like webpack 4, deprecated).
For files that transpile to WebAssembly, make sure to set the module type in the 'module.rules' section of the config (e. g. 'type: "webassembly/async"').
