Unable to run "adb", check your Android SDK installation and ANDROID_SDK_ROOT environment variable: ...\Android\Sdk\platform-tools\adb.exe

When I start the project popup shows "Flutter daemon terminate" and when starting the flutter application it shows the "No Connected Devices Found" dialog box. Then I run flutter doctor -v doctor found issues in:

Connected device (the doctor check crashed)
X Due to an error, the doctor check did not complete. If the error message below is not helpful, please let us know about this issue at https://github.com/flutter/flutter/issues.

I already set up the SDK path as ANDROID_SDK_TOOLS in user variables and tools, and platform-tools in Path. And reinstalled the platform-tools as well but did not solve the issue. I cannot figure the solution if anyone can give me a solution it will be really appreciated.

Tis below log displays in the Event Log:

I still couldn't solve the issue.
