On the legacy wallet page:
https://login.blockchain.com/beta/legacy-pages/forgot-password.html
My phrase gives a Javascript error for

Code:

TypeError: Cannot read properties of undefined (reading 'toLowerCase')

That's an error in the website, not necessarily mean that your recovery phrase is broken.
You can wait for them to fix that until the "beta" in the URL is gone or try to decrypt your wallet files with your password.

If you prefer the latter: Use their "My Wallet Decryption Tool"

Pre-requisites:

Download their decryption tool from the release page: (link: github.com/blockchain/my-wallet-backup-decryption-tool)
For newbie-friendly 'base58 to WIF conversion' download Brainwallet tool by clicking "Download ZIP" below the page, extract it.
(you can use any reputable open-source tool for the conversion if you know any alternative)
In case you want to setup Cold-Storge to spend, download Electrum (electrum.org/#download) and verify its signature (instrcutions).

Steps, Prepare an offline or Air-Gap machine for this:

Copy all those to your offline machine alongside with your wallet files (e.g.: via flash drive), then Open the wallet backup Decryption tool.
Click "Choose File" and select your newest '<walletname>.aes.json' file backup with it, type your password and second password if available.
Scroll-down to see "Decrypt" button, click it. If the password(s) are correct, it will show you your addresses and their private keys in BASE58 format.
...next step is for conversion, steps differ depending on the tool...
Let's say that the result above is positive; In the same offline PC, open the extracted 'brainwalletX.github.io-master' folder, then inside it, open "index.html" with your browser
In that browser window, go to "Converter" tab; in the Source Encoding, tick "BASE58" and "B58Check" in the "Convert To".
Paste your private key in "Source Text" and it should be converted to WIF (Wallet Import Format) in the Result below; do that per private key.

That's it, you got your keys, keep them safe from hackers, do not share those to anyone.
It's's up to you to sweep or import those directly to an online Hot wallet, or setup a cold-Storage in that offline machine (recommended for high amounts).

For Cold-Storage (using the same offline machine for the first part); follow this post: /index.php?topic=5524213.msg64885706#msg64885706
