To Reproduce
Steps to reproduce the behavior:

1. Closed Lens because it wasn't refreshing cluster overview page
2. Start Lens either as regular user or as Administrator
3. Error is displayed

Expected behavior
Application should start normally

Screenshots

Environment (please complete the following information):

• Lens Version: 2024.10.171859-latest
• Electron: 31.6.0
• OS: Windows 11 Pro
• Installation method: Windows installer

Kubeconfig:
No issue with kubeconfig. It used to work for a few days and just crushed now. No recent changes to kubeconfig

Additional context
Lens is very slow to load resources. Tabs behavior is erratic. Sometimes clicking opens new tab, other times it overwrites currently displayed tab

Hi,

I'm dealing with same issue. I tried to uninstall and install Lens again but the same error has been showed at startup.
In addition, each time I'm going to reinstall Lens, I'm facing with this issue #5773

Hello arielmanka,

Thank you for reaching out to Lens GitHub!

This is a bug we are currently fixing. A patch should be released in the next few days for it. It is caused when our storage gets into a corrupted state (due to the aforementioned bug).

Please delete the folder /Library/Application Support/Lens/lens-local-storage-v2 (for MacOS), and restart Lens. You will be able to bypass the problem with it.

In Windows, the folder would be at:

/Users/USERNAME/AppData/Roaming/Lens/lens-local-storage-v2
or
/Users/USERNAME/AppData/Local/Lens/lens-local-storage-v2

Hi @Tixon123,

Thanks a lot for your fast reply. Your solution worked at least for making Lens able to restart.
Currently I have just got another issue which came up before Lens crash. I'm not able to see in Lens my EKS configuration although using kubectl commands I don't have any problems.

Lens complains with the following error:
"Failed to load /api/v1/events: Failed to GET "https://127.0.0.1:52531/api-kube/api/v1/namespaces/art-sdp-server/events?limit=500": Internal Server Error (500)"

@carminoplata can you describe your issue a bit more (or even make a new GitHub issue with more information), such as can you connect to the cluster at all, are you using the AWS EKS or the Local Kubeconfigs section in the navigator? Maybe post a screenshot?

[carminoplata]

The Lens' navigator shows that it is able to connect with cluster but there is something bad in the communication with some internal server:

Regarding the configuraions, I'm using local kubeconfings so the eks configuration is downloaded and added at local configs

[Nokel81]

Would you be able to provide logs for that cluster? You can get them by using the application menu and doing "Help > Export Support Logs". Thanks.

In the attachment, you can find the required logs.
With a fast investigation, I found the following error in the file lens-renderer-root-frame.log
