FTB launcher .exe delete’s itself...

Went to log in after playing in LAN for a week, and the launcher icon was gone. Went to look in files and the whole folder was empty. Did a reinstall and updated java files. Every time I logged into LAN, I got disconnected. My boyfriend then started having the same issues on his pc. Checked for viruses, and nothing has helped. We were playing Revelations at the time. We tried other FTB mod packs and same issue of disconnections, shortly after login.

Are you using the FTB app or the classic/legacy FTB launcher?

Are you using any 3rd party antivirus software?

Are any of you experiencing this also changing your instance location from what is default? I have had this happen twice and both times I had moved my instance from my HDD (default) to my SSD and when i closed the game it would disappear. Come to find out my shortcut path was going back to the default location HDD where there was nothing in because i moved it.
