Locked out of funds: Cannot unstake BNB from using trust wallet web extension with Ledger Nano S & X

This is driving me up the wall. Trustwallet support seems useless and it appears to be the only way to manage staking on BNB these days since the binance staking site only supports trust wallet now. Originally I staked using the BNB Chain Wallet but this is no longer supported on the staking page.

There are two approaches to unstake both don't work and both involve the trust wallet browser extension (latest 2.9.3):
Method 1 - Unstaking via bnbchain.org page (link above):

1. Click connect wallet and connect via trust wallet
2. Click 'My Staking' also on the top right
3. Click 'undelegate' button
4. Enter amount to undelegate, click undelegate on the modal
5. Trustwallet prompt comes up > Click confirm
6. Error: 400 Network error shows up:

Method 2 - Unstaking using only trust wallet extension

1. Open trust wallet extension
2. Click on your BNB holdings on Binance
3. Click on 'Native staking' grey box
4. Should take you to a new page, click 'unstake'
5. Enter amount to unstake, click 'Unstake now'
6. Click confirm
7. Error: Cannot read properties of undefined (reading 'validatorAddress')

Basically I'm locked out of my funds considering I can't unstake which also means I can't migrate to Binance Smart Chain.

Tried multiple browsers (Brave, Chrome, Edge) and multiple hardware wallets Ledger Nano S & X.

Are there any apps which support Ledger and can unstake BNB without needing trustwallet? I did look and couldn't find anything.

Any ideas welcome because I'm running out.
