i can't sinc anymore with the last version, anyone have the some problem?
No, i can sync whether on mainnet, testnet or signet. You might want to ask help on "Bitcoin Technical Support" board while providing some information (e.g. debug log, how do you connect to internet).
i didn't change anything about internet connection or firewall therefore it's not that, there was a warning about consensus when i switched from 23 to 24 version, then the warning disappeared and now it's not synching anymore
If you haven't changed anything regarding your internet connection or firewall settings, the issue with the latest version of the software could be causing this. It's possible that there are compatibility issues with the current version of the software and your system, resulting in the synching problem.
You can try the following steps to fix the issue:
1. Check if your Blockchain data is corrupted or your system is out of sync.
2. You can also try backing up your wallet and updating to the latest version of the software.
3. If updating doesn't work, try uninstalling and reinstalling the software.
