Unity 2018 crashes everytime I open project (Please Read the question!)

Hello everybody!
I just get to the point. First I was working with unity 2018.2.1f1 and in the middle of the project it was kept crashing. after 2018.2.3f1 came out I installed it and same problem but worse!
It crashes on startup. then I updated to 2018.2.4f1 and I’ve still have this problem.
I’ve deleted the temp and library folder but it didn’t help.
Even starting a new project face this same problem! now I have a project to attend to but I can’t work!
What should I do?!
PS: 8GB Ram and Nvidia GTX950m and windows 10 pro.

Just by opening the editor-prev.log file I could clearly see an error message saying:
“Cancelling DisplayDialog because it was run from a thread that is not the main thread: Fatal Error! Could not allocate memory: System out of memory!” then google searching it I could find the topic:

I understand you don’t know why this is happening and is asking for help, but please try to be a little more pro-active if you want to be a good developer.

This is the log.
See if you can find the problem!
