I encountered an error when using the Polkadot.js UI. When I click on a link, the following error appears:

Steps to reproduce:

1. Open the Polkadot.js UI.
2. Click on the block number from explorer menu.
3. Observe the error.
4. This seems to be related to C.proofSize.toBn not being recognized as a function.
