I had a similar issue, check your Content-Security-Policy header in the response for the html page, you need a workers-src 'self' block: data: entry if you have explicitly set the CSP header.

For example in nginx:

add_header Content-Security-Policy "default-src 'self' 'unsafe-inline' blob: data:; script-src 'self' 'unsafe-inline' 'unsafe-eval'; workers-src 'self' blob: data:;";
