Hi.
Blender all the sudden refuses to run. It gives an error that says it cannot find ur_win_proxy_loader.dll in the Blender folder.
Yesterday it was fine. I didnt install any addon recently. I didn’t install anything on the computer at all.
I tried running sfc /scannow in the cmd. Reinstalling blender. I updated my driver. Restarted my computer. Nothing seems to work. The last version I can start is 4.1. Anything newer crashes.
I have no idea what is wrong. Please help.
Hi there,
From some research it would appear that this DLL is associated with Intel’s Unified Runtime, do you have an Intel CPU or GPU? If so I would suggest updating the drivers of your CPU / GPU.
You could also try resetting your Blender configuration, to make sure it’s not a corrupted file.
I have intel processor. Intel says: No supported driver or software updates are available for your system.
Interesting, did an update occur between the last time you used Blender and now? Also is it your CPU or GPU that is Intel?
I would suggest trying to run Blender with factory settings, by runnng this command
blender --factory-startup
You could also try reinstalling the same drivers using device manager.
There was a windows update about 2 days ago. But blender worked yesterday.
OK, I just edited my post to contain some more information, would you mind taking a look at that?
The same happens
Hmm 
, do you have a dedicated graphics card or not? If you have a dedicated graphics card do you know if Blender is set to use it or the CPU?
I have a geforce rtx 4070 ti
My processor is intel i9-12900f. I always use it when I can. But that involves the renderer only, no?
By that do you mean you generally use the GPU not the CPU?
Also if you go into your Blender application folder, is the ur_win_proxy_loader.dll file present?
Can you download the portable .zip version of Blender and check if it runs?
The file is not present. It is also not present in the 4.1 version. However that file might be hidden. Right now I cannot show hidden files because a bunch of features are missing on my file explorer and I have no idea how to access them. Very strange. The entire ribbon menu is missing and there is no button or arrow or anything to bring it back. I have no idea why this is happening.
yes, I did try that and it gave the same error.
I did a restart… again. The ribbon is back in the explorer and blender runs now. Thanks for helping. Unfortunately I dont know what caused this still. So if someone has the same problem just try everything and restart like 3 times. 
Windows update probably fudged something then. Maybe try uninstalling and reinstalling the Windows update as a last resort, could also be that there are some updates still running in the background that are not done.
