Later, firefox crashed again, now it works ...


Thank you!

According to Gemini:

This error message "TypeError: Blob constructor: ArrayBufferView branch of ((ArrayBufferView or ArrayBuffer) or Blob or USVString) can't be an ArrayBuffer or an ArrayBufferView larger than 2 GB" means you're trying to create a Blob object in JavaScript using an ArrayBuffer or ArrayBufferView that is larger than 2 gigabytes, which is the current limit for such operations in most browsers. 
Explanation:
Blob and ArrayBuffer:
A Blob (Binary Large Object) is a data object that represents raw binary data in JavaScript, and an ArrayBuffer is a raw binary data buffer that can be accessed using TypedArrays. 
Size limitation:
When creating a Blob from an ArrayBuffer or ArrayBufferView, the browser usually enforces a maximum size of 2GB. 
What causes this error:
Large file upload:
Trying to upload a file larger than 2GB directly as a Blob using an ArrayBuffer. 
Large data manipulation:
Attempting to create a Blob from a large in-memory ArrayBuffer that exceeds the 2GB limit. 
How to fix:
Chunk the data:
If you need to handle files larger than 2GB, split the data into smaller chunks and create separate Blobs for each chunk. 
Use a streaming approach:
Instead of loading the entire file into memory as an ArrayBuffer, consider using a File Reader to read the data in chunks as a stream and create the Blob progressively. 
Check browser compatibility:
While the 2GB limit is common, be aware that different browsers may have slightly different constraints. 

Seems like large file sizes requires chunking and file system management, which is currently missing in the script functionality.

Unfortunately I'm pretty busy recently so I will keep this open for a while and look forward to someone else adding this handling later.
