On-chain funds stuck (Script failed an OP_EQUALVERIFY operation) #8804

1. I connected to my Core Lightning node with Zeus wallet over CLNRest
2. Generated and address in Zeus to fund the wallet.
3. Sent funds to that wallet.
4. Tried to open a channel with said funds and got an error:

Error broadcasting transaction: error code: -26\nerror message\nmempool-script-verify-flag-failed (Script failed an OP_EQUALVERIFY operation), input 0 of ...

6. After that I tried to make an on-chain transaction to move the funds to another wallet, but the same error occurred.
7. Then I tried to use lightning-cli to withdraw the funds. Same error.

Currently:

1. I can see the funds in the addresses that lightning-cli listfunds lists.

What causes this?

Core Lightning version: v25.12
