Raspberry pi 2 runs fine for a month and then starts freezing more and more

I'm running Raspbian Buster Lite, headless on a raspberry pi 2 and this problem actually started around the end of 2019. Every time this start happening I do a fresh install and I'm basically good for a month and then the problem starts again, it starts with freezing once a day but very quickly it's up to multiple times a day (5-6 times). With freezing I mean I can't do anything to reach it and my only option is a hard reset.

I included syslog (log is from moment it freezes but seems like logs from starting up) and debug log but have all other logs if needed.
Thanks in advance.
