I'm found that crash reports became unreadable because of obfuscation. From crashlytics log i'm found exception

Has anyone encountered this problem
I'm quite sure that problem is started when i'm installed standalone canary build of Android Studio 4. Many thanks to mr. Martin Zeitler, his answer
prompted me in the right direction. The problem was in root gradle properties ~/.gradle/gradle.properties file.
When working with Gradle, we typically check the gradle.properties file within the project directory. However, there’s another important gradle.properties file that resides in the system-level user folder. This file can also influence your build behavior.
📂 Steps to Locate the System-Level gradle.properties File:
🖥️ On macOS:
1. Open Macintosh HD (your root drive).
2. Navigate to the Users folder and open your username folder.
3. Press Cmd + Shift + . to show hidden files.
4. Look for a hidden folder named .gradle.
5. Inside .gradle, you’ll find the gradle.properties file.
🪟 On Windows:
1. Open the C: Drive.
2. Navigate to Users → YourUsername.
3. Enable hidden files from the View tab in File Explorer.
4. Locate the hidden .gradle folder.
5. Open the gradle.properties file inside it.
⚠️ Note:
• This system-level gradle.properties can override or supplement project-level properties.
• Be cautious when editing it, especially in shared or CI environments.

systemProp.http.proxyHost=
systemProp.http.proxyPort=80
systemProp.https.proxyHost=
systemProp.https.proxyPort=80
and removing systemProp variables make uploading deobfuscation works back.
