You have 4gig ram and only nearby 450mb free at early start of obs.
Try to close any other app and try to start obs with admin privileges.
If you want to start over with a fresh install you should remove the directory
C:\Users\[YOURUSER]\AppData\Roaming\obs-studio
Not only obs updates should be mentioned, win-10 updates coming in over the last months may change or worsen the status quo, (unfortunately) too.
The last log entry is during init of the gpu/graphics. Maybe a driver problem, so.
