I got the same issue. Around 800 hours on the game without any problems. Only on community servers and zero community bans. I have around 300 hours of clips and videos of nice kills, shots, or fun moments. And I have never been called out as a cheater. I never needed to prove that I'm not cheating (tbf I played on high pvp server with 0,8kd so that might explain it) so last few weeks I have been playing on Hardcore Namalsk and on almost empty server. I had to work for long days and I didn't have time to play for few days and when I came back I got banned. The ban came just when I opened steam. I know this because I was looking on my Steam profile on my phone at the same time when I was starting my PC and I wasn't banned before I opened steam on my PC. So I know it has to be something on my PC which is triggering it. I have sent mail and contacted support but I haven't heard anything about them.
I have all possible virus protections on and I did full scan on my PC. Only thing that it flagged was one data analysis tool which I use for work.
As I have read about this topic more I have found out that lot of people who are falsely banned have had rtx 3070 gpu which i also have.
Also my bios wasn't the latest version.
I wouldn't care to get banned but I'm playing on my laptop which was 2,5k€ and since it's HWID ban that laptop is basically useless to me because I almost only play DayZ.
Also the fact that they can ban someone and not provide any information why they were banned is incredibly frustrating. (I know cheat developers would love to know why their cheat got detected). But they should at least say something regarding the ban.
Edit.
