Failed to join the game! OFline mode

Today i log in my game and see my hell Sorc 65lvl is gone on single player menu. and when i tray to connect in any signle player game i get this msg and troll me back to the menu… if i make new charther again same problem dont let me i play single player … ???

This appears to happen after a crash, or if the games’ files are corrupted. One solution to try is to delete the file for the shared stash. Normally it should be located here:

C:\Users(your user name)\Saved Games\Diablo II Resurrected\SharedStashSoftCoreV2.d2i"

If deleting the shared stash file doesn’t resolve your problem then the issue is most likely with the character save file. There is currently no known way to fix corrupt save files.

i delete stash and dint help so i delete my charther wich dint show me in game and problem was fix …
So now i need to start from begining ?? and what i can go to hell again and this one happen again?so every 2-3 days i need to start from begining?
