I've been facing this issue since today. Yesterday I updated Android Studio from 3.4 to 3.5 and it was working fine but since today it's been crashing on startup. When I start it shows the splash screen and then tries to load the project and suddenly closes or crashes without showing any error message. What should I do? Is there any error log I can refer to understand what is the problem, please help me with this.
After updating Android Studio to 3.5, I faced like you. If you are using anti-virus softwares.
Try close any anti-virus software or add Android Studio 3.5 to whitelist
Below was my problem and finally I come to know Android Studio is crashing because of it.
