server startup stops at cod4x_patchv2

Server version 21.2. The server worked well, but after restarting the PC it was not possible to start it again! The server stops at Loaded fastfile ‘cod4x_patchv2’ in 15ms (0ms waiting). I tried to completely reinstall the server. Start with the standard config, but it didn’t help. If I send the command in the server console map mp_crash, then the map starts and I get Resolving cod4master.activision.com
cod4master.activision.com resolved to 185.34.107.159:20810
