Where is fivem

why did me and my friend’s fivem copies randomly disappear???

Because you’re both running an anti-virus that detected FiveM files as a virus so it deleted FiveM

I’ve had fiveM since June 2017 and this is the first time I’ve had this happen, and nothing happened because I haven’t ran an antivirus scan between the last time I played. My friend’s game is still there, but he has a “downloading of” error now constantly

The anti-virus blacklists change all the time

Anti-virus software actively scans files in the background. This is what triggered it.

Also related to anti-virus

I also specifically set both of our antivirus programs (we both have malwarebytes) to both bother 5m

try disabling them and try it again.

Also, next time post in technical support and fill in the support template.
