I had the same problem as you and I looked everywhere for answers, but couldn't find much. I saw a comment on here awhile back that said that they changed the language of the game through Steam/Epic then changed it back and they haven't had any beagle/marmots since. I tried it and I got the same results for about 3 days before I started getting them again. Your experience might be different so maybe try that. I also saw to test your RAM with MemTest86 to see if there are any faults in your RAM that could be causing the issue. MemTest86 is free to use and there are some videos online on how to use it. Hope this helps.
