OneLake Explorer crashes after login
Hi all
We have set up OneLake Explorer for more than 10 users and it has worked, but on one User it crashes everytime when he logs into the app.
What caught my eye was this error in debug.log:

Does someone know what could be the problem? The user is configured same as all of our Users.
Here is the whole debug.log

Hi Anonymous,
Thanks for reaching out to the Microsoft fabric community forum.
It looks like your oneLake explorer is failing to initialize for a specific user because it cannot find the user details in the OneLake service. The error message shows that the user authentication is failing, and the service does not recognize the user’s identity. As the same setup works for other users, it suggests that the issue is specific to this user’s identity or permissions in OneLake. Please check if the user account is properly provided in OneLake. The user may not have been correctly added to the necessary Fabric workspace or OneLake storage permissions. Also check if the user’s Azure AD token may be corrupted, expired, or missing necessary permissions for OneLake.
I would also take a moment to thank nilendraFabric, for actively participating in the community forum and for the solutions you’ve been sharing in the community forum. Your contributions make a real difference.
If I misunderstand your needs or you still have problems on it, please feel free to let us know.
Best Regards,

Hello Anonymous
try
Delete the problematic user’s OneLake profile directory at `%USERPROFILE%\OneLake - Microsoft`.
• Clear cached credentials via Windows Credential Manager for OneLake-related entriesThank you for your answer. Unfortunately that did not help.
I deleted the Userprofile multiple times and rebooted the laptop but no success, I get same result. OneLake Explorer crashes immediately after user login.On the Windows Credential Managed I did not find any OneLake-related entries.
Hi, I have the same problem. Did you manage to fix it?

Hi Anonymous,

Thank you for your patience and look forward to hearing from you.Same here. I can install it, it asks to log in, and then it's nowhere to be seen. Tried to install it as admin, tried to delete the synced folder, to now avail. Very frustrating. Not good for product image.
