I updated my Mac Pro to 26.1 a few days ago and now I am unable to open Lens. It just opens the loading box and sits and sits.

I can only assume this is related to the OS upgrade but I’m not 100% sure. Just posting to see if others have experienced this at all.

Thank you!

Hi @karl.kofmehl,

sorry you’re running into this after the upgrade, and thanks for reporting it.

We’ve identified an issue that can prevent Lens from starting in some cases after updating the OS. A fix is already prepared and will be included in the next Lens Desktop release.

In the meantime, this workaround should unblock you:

1. Close **Lens.app** if it’s open.
2. Open **Terminal.app** and run:

```auto
mv "$HOME/Library/Application Support/Lens/extension-store/lenscloud-lens-extension/auth-token-store.json" \
"$HOME/Library/Application Support/Lens/extension-store/lenscloud-lens-extension/auth-token-store.json_backup"

```

1. Open Lens again – you should be able to re-activate/sign in and continue using Lens.

This only resets a cached authentication token; your clusters and other settings are not removed.

If this doesn’t solve it, please let us know so we can investigate further.

Quick update: we’ve just rolled out a new Lens Desktop release that includes a fix for this startup issue.

Please [update to the latest version](https://lenshq.io/) and try again. If Lens still gets stuck on the loading screen after updating, let us know and we’ll dig deeper.
