Description

When attempting to run my Blazor WASM application on Safari iOS version 15.4, I encounter the following errors in the browser console:

MONO_WASM: AllowRange:3e code generation failed: CompileError: WebAssembly.Module doesn't parse at byte 11: can't get Function local's type in group 4, in function at index 0 (evaluating 'new WebAssembly.Module(p)') Module@[native code]
MONO_WASM: get_Cache:0 code generation failed: CompileError: WebAssembly.Module doesn't parse at byte 11: can't get Function local's type in group 4, in function at index 0 (evaluating 'new WebAssembly.Module(p)')
Unhandled Promise Rejection: RuntimeError: Out of bounds memory access (evaluating 'St.mono_wasm_invoke_method_bound(e,t,n.address)')

Reproduction Steps

• Open Safari on iOS 15.4.
• Navigate to the Blazor WASM application URL.
• Observe the browser console for errors.

Expected behavior

The Blazor WASM application should load and run without errors on Safari iOS 15.4, similar to other supported browsers.

Actual behavior

Encounter runtime errors related to WebAssembly.Module and out of bounds memory access, preventing the application from functioning correctly.
