Steps to Reproduce

Also linking to these issues for completeness:

• https://github.com/swc-project/swc/issues/8944 (where the error happens)
• https://github.com/open-telemetry/opentelemetry-js-contrib/issues/2199 (underlying cause)

When bundling code with @sentry/...@^8 you will see hundreds of errors that look like the following if your bundler is using @swc/core

  ERROR  failed to read input source map: failed to parse inline source map url
utils.js.map
Caused by:
    relative URL without a base
    at /Users/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/swc-0.273.27/src/lib.rs:385

Please use the links above to understand where the error happens versus what is actually causing the error.

It would be great to get some support from the Sentry team to have these issues resolved.
