You are going to need to provide more information, such as which version and which browser.
My guess is that your wasm file is corrupt, as this error has never come up in many hundreds of tests and has never been reported before.

Hi Stephan,
I am using Chrome Browser with version 119.0.6045.200 and this issue occurring while push the files on IIS, on local its working fine.

... this issue occurring while push the files on IIS,...
Perhaps (just speculating) IIS needs to be configured with the proper mimetype for wasm files? Right now it appears to be attempting to serve them as HTML files.

My guess is that your wasm file is corrupt ...
The hex from your error report decodes to:
<!DO
which looks like the first 4 bytes of an HTML5 DOCTYPE header. You have a file named sqlite3.wasm which is not actually sqlite3.wasm.

I am facing the same issue.
"Somewhere" in IIS you need to tell it that files named *.wasm have mime type application/wasm. It's apparently defaulting to a different mime type for such files.
