shaders don't compile

4.27 shader compilation froze. It doesn’t go any further, let’s say 223 and that’s it. I left it for three hours to make sure there was a problem. Even reinstallation, deleting the config folder, clearing and moving the cache folder, and generally clearing this version from the PC did not help. Even removing the colon before it didn’t help r.XGEShaderCompile = 0. Also because of this, the editor freezes during the build. I would be grateful for a speedy response to fix this problem.
