No way to remove the tool entry that was failed to get added from featured tool list

[sangee2004]

Electron build - b6c00b533

Steps to lead to this problem:
I had tried to add Hubspot tool to an existing assistant which failed due to - #434
After this failure , when I try to chat with this assistant , I am getting the following error

Edit page for this assistant shows no tool entries.

Assistant script file (from gateway) shows github.com/gptscript-ai/tools/apis/hubspot/crm tool being present.

Name: github-agent1
Description: An agent to help you with GitHub related tasks using the gh cli
Type: Tool
Tools: sys.exec, github.com/gptscript-ai/tools/apis/outlook/mail/manage, github.com/gptscript-ai/tools/apis/slack/write, github.com/sangee2004/testrepo/context/direct, github.com/gptscript-ai/tools/apis/hubspot/crm
Context: dynamic-instructions
Chat: true

You are a helpful assistant named New Assistant. When you first start, just introduce yourself and wait for the user's next message updated

Name: dynamic-instructions
Type: Tool

#!/usr/bin/env bash

echo "The following is the help text for the gh cli and some of its sub-commands. Use these when figuring out how to construct new commands.  Note that the --search flag is used for filtering and sorting as well; there is no dedicated --sort flag."
gh --help
gh repo --help
gh issue --help
gh issue list --help
gh issue create --help
gh issue comment --help
gh issue delete --help
gh issue edit --help
gh pr --help
gh pr create --help
gh pr checkout --help
gh release --help
gh release create --help

Expected Behavior:
When there is a failure to load a tool , is it possible to not have it added to the assistant to begin with ? Or get it removed from the assistant when the failure is encountered?
If this is not possible , then we should be able to show this tool as being in bad state and provide user the ability to get it removed.

The linked issue mentions that if an invalid tool exists on the assistant, then the entire tools section of the edit screen is blank.
