Hey Guys, Just a quick update—I was able to successfully reproduce the issue locally using Chopsticks. However, I haven't identified anything explicitly wrong yet. I tested the sudo page on both Acala, Astar and this specific chain, and interestingly, it works perfectly fine on Acala and Astar.

So far, I haven’t found any significant differences between these chains (for sudo), but I’m continuing to investigate. One thing is certain—the issue does exist, and I’ll keep digging to pinpoint the root cause.

Fixing with #11426

Now it correctly throws the expected error on the Sudo page, similar to Extrinsics page.
