You have a freakishly old system. Judging by the resolution conundrum, Windows is probably terminating the game for 1 of a few reasons:
1) Heat. That old of a system probably has heat issues, so your programs may be terminated due to overheat. Usually your whole PC goes into sleep mode, though, so this *probably* isn't the cause.
2) VRAM. You only have 512 and ReShade uses some to run. Generally you'll stutter a lot before crashing if this was the case, though, so this *probably* isn't the cause.
3) RAM. You only have 2 gigabtes. That's scarily low. I'm using 2.3 just typing this on my browser with a few small background programs running. I have 8 gigabytes, so I've only had issues when I messed around with page files, but that taught me that if Windows notices that your RAM is almost completely full with no other memory, it'll start terminating/suspending programs. I'd bet that this is your problem, as 2gb of RAM is how much a
smartphone has nowadays, not a pc.
Note that it's not worth upgrading your pc in any way, so you'll just have to close as many bg programs as you can or something.
4)CPU. You have what I assume to be an old Pentium/AMD cpu, which is in no way comparable to anything modern. However, running out of CPU will have similar effects to running out of VRAM.
