For your issue, please follow the below steps:
1- Re-install the extension. You can use the sequence version scripts to do so. Keep in mind, if you used a KEK to encrypt, you'll have to use the KEK encryption script pointing to the same key you used to encrypt your VM initially. All other variables will be the original ones used to encrypt the VM, i.e. (Key Vault, Keys).
2- If re-installing the extension works, please go ahead with the recommended workflow to Decrypt & Remove the ADE extension.
If the re-installation of your extension doesn't work please let me know.
As an additional note, I tried repro'ing your issue and wasn't able to. Which means, the error message you provided might be correct when it says "or wait for an ongoing one to complete."
Reproduction Steps Taken:
-I encrypted my VM, removed the ADE extension, and tried to decrypt the VM. However, as you can see, the Disable command ended up working.
-For this second repro, I ended up re-installing the ADE extension using the same variables I used to encrypt my VM originally. I was able to Disable/Remove the extension.
Please let me know if you run into any issues.
