web3py EthereumTesterProvider - Basic transaction fails

Question

On the web3py EthereumTesterProvider blockchain, I send 2 ethers from the first test account to the second one. The python program ends normally but the transaction seems to fail :

the status of the transaction receipt ('status': 0), which I guess means failed.
the balance of the 2 accounts is not updated after the transaction.

pip config (windows 10) :

web3py (5.31.3)
eth-tester (0.8.0b3)

Code:

from web3 import Web3, EthereumTesterProvider
from pprint import pprint

w3 = Web3(EthereumTesterProvider())
print(f"{w3.isConnected() = }")

print(f"\n{w3.eth.get_balance(w3.eth.accounts[0]) = }")
print(f"{w3.eth.get_balance(w3.eth.accounts[1]) = }")

tx_hash = w3.eth.send_transaction(
    {
        'from': w3.eth.accounts[0],
        'to': w3.eth.accounts[1],
        'value': w3.toWei(2, 'ether'),
        'gas': 21000
    }
)
print(f"\n{tx_hash = }")

print("\ntx_receipt = ")
tx_receipt = w3.eth.wait_for_transaction_receipt(tx_hash)
pprint(dict(tx_receipt))

print(f"\n{w3.eth.get_balance(w3.eth.accounts[0]) = }")
print(f"{w3.eth.get_balance(w3.eth.accounts[1]) = }")

Traces:

w3.isConnected() = True

w3.eth.get_balance(w3.eth.accounts[0]) = 1000000000000000000000000
w3.eth.get_balance(w3.eth.accounts[1]) = 1000000000000000000000000

tx_hash = HexBytes('0x72345d1c23a10ac3849e1f8e53b517da8200e58ab211ebaf44df732f6f8a29af')

tx_receipt = 
{'blockHash': HexBytes('0xadfcec5788a8757a5eed6aeee15c997a6b75a612fa4919a878b02a69d04f8a0c'),

 'transactionIndex': 0,
 'type': '0x2'}

w3.eth.get_balance(w3.eth.accounts[0]) = 1000000000000000000000000
w3.eth.get_balance(w3.eth.accounts[1]) = 1000000000000000000000000

Please also note that this code works with ganache when I change the instance of web3 like that :

w3 = Web3(Web3.HTTPProvider('HTTP://127.0.0.1:8545'))
