I've recently updated my Android Studio to 3.0 rc2 using Beta channel of the update section inside the application.
Today I wanted to use Android Device Monitor where an exception happened and saved to log inside sdk folder.
The log is this:

I don't know how to handle this error and I need a way around. I'll be glad with any suggestion to solve it without mentioning "download stable version" and downgrade.
UPDATE: After I tried to update to Stable version through the Stable channel of update section I get error that some files missing
gradle/m2repository/com/android/java/
gradle/m2repository/com/android/java/tools/
gradle/m2repository/com/android/java/tools/build/
gradle/m2repository/com/android/java/tools/build/java-lib-model-builder/
gradle/m2repository/com/android/java/tools/build/java-lib-model/
I'm trying to update every single module so maybe I could solve this issue
UPDATE-2: After cancelling previous error and running the Android Studio, It seems to be updated but the error is still there, here is the error after updating to Stable version:

UPDATE-3: After A LOT of searching, I found a solution but it's not the answer so I added this update to question.
I can run the Android device monitor manually by going to /sdk/tools/ and run the monitor.bat file by cmd or powershell and now I have access to this feature, but even now, the Android Studio can't open it for me!!!!
Please if anyone can help me post an answer telling me a workaround this problem.
After a lot of try and catch! I finally fixed the issue. Android Studio 3.0 is not fully support JDK 9 After installing JDK 8 on my system and set it as JAVA_HOME variable and restarting the system everything is working now. I got it because I wanted to install Nativescript and I couldn't cause it only supports JDK 8. that was my first clue
Set JAVA_HOME variable to JDK 8 directory and everything will be okay
