I've faced the same issue with Authorize.net AcceptJs payments in Sandbox mode.

After debugging, I've found that the SHA512 key is not matched with the generated transaction key. The issue is because of the Float value of the transaction amount.

I've fixed this issue by overriding the generateSha512Hash() of the AcceptJs core module in my custom module.

private function generateSha512Hash(
    string $merchantKey,
    string $merchantApiLogin,
    string $amount,
    string $transactionId
): string {
    if($amount == floor($amount)){
        $message = '^' . $merchantApiLogin . '^' . $transactionId . '^' . $amount . '^';
    } else {
        $message = '^' . $merchantApiLogin . '^' . $transactionId . '^' . (float)$amount . '^';

    return strtoupper(hash_hmac('sha512', $message, pack('H*', $merchantKey)));

Hope this helps.
