[Bug]: Review transaction details not loading after closing 'Buy token' window from Insufficient funds alert

**Describe the bug**

During a transaction with insufficient funds for gas, if the user clicks on the 'Buy Native token' button from the alert message and then closes this modal, the Review transaction screen is not loading any details.

If the app is locked, it does not fix the screen, but it can be restarted and the issue is fixed.

**Expected behavior**

Review transaction screen to load
