blockchain.com BTC wallet "affected by a third party software security issue"

[postcd]

https://login.blockchain.com/en/#/home is telling me:

The following legacy addresses have been identified as possibly affected by a third party software security issue. To secure these funds, click the ‘Transfer Funds’ button below. This will mover the funds from the legacy addresses into new, secure addresses in your DeFi Wallet.

It is my main BTC wallet, there is only option to "Transfer funds". When i click it, it says: There was an issue transferring your funds. Please contact Support.
Then i end up at https://support.blockchain.com/hc/en-us/sections/4585337100180-Account-Security

Do you have any security-wise suggestion. Is now good time to import my wallet into an Linux desktop wallet app https://bitcoin.org/en/choose-your-wallet?step=5&platform=linux&important=transparency ? I am very rarely using the wallet, just storing my BTC there.

Importing is not good enough. You must also move all of the funds to a new address, that's why it is showing you this message.

I do not know exactly what the security issue Blockchain.com is trying to tell you, but I suspect that it has something to do with this event: [Warning!]Numerous BitcoinJS -based wallets are still under the threat.

If you have a seed phrase backup of your blockchain wallet you can import it to Electrum and move your funds to your new wallet.

Make sure to move your funds to your wallet that you know is safe like Electrum cold storage. Take note Electrum also supports Linux OS and it is safer than Windows OS but both OS should be safe just make sure never connect your PC online.

You can read the documentation about Electrum cold storage below.
