I had this bug and I do not know what helped me, but I will just say what I did.
1. After receiving this "Message", I did a file integrity check and the rest of the checks in turn, then I launched tarkov just in case (I deleted it a long time ago and was waiting for the Spt Aki update all the time)
2. Then I rebooted Windows, it didn't help me, I did another check, found this forum and looked at the absolute emptiness, got upset and went to play Metal gear, which I recently bought.
3. Out of desperation that answers appeared on the forum, but they did not help me, I deleted the text files that remained after previous installation attempts and I started installing Spt Aki. The installation has started and is still in progress.
(It was written through a translator, so maybe not everything will be clear, but I didn't do anything particularly magical.)
