Error from anti cheat

hello . 2 days in a row i got this message from the game at every first battle of the day . If i relog the game run normal and without any error . Anyone know what is it ? it started 2 days ago .

Quick googling the ‘EAC C0000001 War Thunder’ pulls out a few suggestions.

Verify files in the launcher or steam. Repair the EAC service by running the EAC setup in the game folders EAC folder as admin.

And if that doesn’t fix it, delete the EAC folder, verify files and launch the game again and it should redownload the missing files that you deleted.
