Blank screen on startup

[khushil]

So this morning I started ComfyUI as normal, or so I thought, but for some reason when ever I go to the browser there's nothing there. Just a blank screen with no menu and none of the keys/clicks work.

[Nebuluss]

Has anyone solved the problem of empty window at startup?

Yesterday I worked quietly in Comfyui, but today at startup where my workflow should appear just a blank screen, there is no manager nothing at all, the CMD line shows no errors, should all work but it does not work.

[bramdsgn]

same here, the issue is unclear, is there a fix ?

[antoh116]

I never found a workable solution

[jejejejajaja]

try checking cmd log. mine was because of Kaspersky antivirus. it might work when you turn off antivirus.

Guys, anybody found the solution? Antivirus doesn't change anything for me.

Any Luck ?

Generally, such phenomena occur in the following cases:

1. Communication or file access is being interfered with by antivirus/firewall.

   • Try disabling the antivirus/firewall in each environment and test. After identifying the problem, you can add exceptions for ComfyUI only.

2. File loading is being interfered with by browser extensions.

   • Try installing another browser with no extensions and test.

3. An abnormal browser cache state is causing persistent errors.

   • Delete the local storage items for 127.0.0.1:8188 in the browser's developer tools.

4. Loading has been interrupted due to an error in a custom node.

   • Try disabling all custom nodes and test.

For other specific errors, in the case of Chrome, you need to diagnose by opening F12 (developer tools) and checking the error messages printed in the console or the loading status of files in the network tab.

In my situation, If anyone remember there was a windows problem all around the world last week and some windows users got affected ( like me) after update my windows everything came back.
