This might be helpful information for others, as it cost me too much time to resolve.
I recently updated to Rider 2022.3.2 and afterwards I could no longer debug Blazor Wasm apps in neither Chrome nor Edge. The apps functioned correctly when Run. The browser error was:
NotSupportedException: Required Plugin ‘ProfilingFeature’ was not registered
Using another computer with the previous Rider 2022.3.1, debugging worked without an issue.
Eventually, I resolved the problem by configuring ServiceStack profiling, as described here:
No idea, why a Rider update required me to add a ServiceStack profiling configuration, but with the above added to my application, browser debugging worked again.
(FYI: Windows 10; Net7, ServiceStack 6.5.1; Blazor WASM)
As far as I know, I am not listening to diagnostic events. But, if my app was, why would browser debugging in the previous Rider work? There were no code changes between updating Rider and browsers were at their latest releases.
I wont be able to tell from here, maybe you have a dirty cache and its using old binaries.
When issues like this happen I recommend clearing out all binaries and caches so you can have a fresh start, by deleting .idea, bin and obj folders and performing a full rebuild.
