Chainweaver stuck on Preview section when submit a new module or update it

I can send all the transactions to a contract without problems, but if I try to send a new module or to update it the program crashes and no buttons respond anymore.

I see the KDA being taken from my account, but the transaction is not always successful.

I'm talking about the **Testnet** and I'm using Chainweaver (app, not desktop) from MacOS Monterey 12.4
