The topology that includes missing VMs can't be loaded in GNS3. How can I fix it?

The above error occurred because the Kali Linux VMX file was mistakenly deleted from my GNS3 topology

If the VMX file (which is the configuration file for VMware virtual machines) of your Kali Linux VM has been mistakenly deleted from your GNS3 topology, you can recover from this situation by following these steps:

Locate the Original VMX File:

• Check your computer's recycle bin or trash folder to see if the VMX file was moved there when deleted.
• If you have backups of your GNS3 projects, check those backups for the VMX file.

Restore from Backup (if available):

• If you have a backup of your GNS3 project that includes the Kali Linux VM, you can restore the VMX file from there.

Recreate the VMX File:

• If you cannot find the original VMX file, you can recreate it:
• Open VMware Workstation or VMware Player (or whichever VMware product you are using).
• Create a new virtual machine configuration for Kali Linux within VMware. Customize the virtual hardware settings (CPU, RAM, network adapters, etc.) to match your original configuration as closely as possible.
• Once the VM is configured, VMware will create a new VMX file.
• Use this new VMX file in GNS3 to reconfigure your Kali Linux VM

In this case, I recreated the VMX file by installing Kali Linux within VMware, and then I modified the path in the topology file as shown (opening Notepad)        

After this modification, the topology has successfully loaded in GNS3
