You can't post the log here, but you can post it online somewhere like a file sharing website or a cloud drive, then I can take a look.Here's a few sites you can upload it to, which do not require you to sign up first:https://uploadfiles.io/ - free, no sign-up, can handle large log files
https://paste.ee/ - fast, no sign-up required (some log files will be too large for it though)
https://zerobin.net/ - bit clunky, but can handle huge files, no sign-up required

You upload it there and then post a link to the file here. Then I'll take a look as soon as I can. :)

You're running out of memory. With only 4 GB RAM you should avoid workshop content, if you aren't already. You will also want to set up a custom size for your pagefile. I recommend 32 GB. That should stop the crashing.https://steamcommunity.com/sharedfiles/filedetails/?id=2114415052&searchtext=pagefile
