Azure Toolkit For IntelliJ not working

After installing the Azure Toolkit For IntelliJ plugin, have restarted the IDE. Plugin is installed successfully but could see below error.

java.lang.NullPointerException: Cannot invoke "com.microsoft.azure.toolkit.intellij.java.sdk.utils.RuleConfigLoader.getRuleConfigs()" because the return value of "com.microsoft.azure.toolkit.intellij.java.sdk.utils.RuleConfigLoader.getInstance()" is null

Azure login via the toolkit is also failing with below error.

Azure: Failed to load subscriptions. Unable to find valid certification path to requested target. 

Call Stack: 

- Load subscriptions 
- Reload subscriptions 
- Login with (OAUTH2)
- Sign in to Azure 
- Sign in

IntelliJ Version - IntelliJ IDEA 2025.1.3 (Ultimate Edition)
Azure Toolkit For IntelliJ plugin version - 3.95.0-2025.1
OS - macOS Sequoia 15.5

Start with the DisableAutoCompleteCheck.buildVisitor stack-trace location at DisableAutoCompleteCheck.java:40 and inspect how RuleConfigLoader.getInstance() is initialized. Separately trace the Azure sign-in flow that reports an invalid certification path. Done means the inspection no longer throws the reported exception and Azure login can load subscriptions on the stated IntelliJ and macOS versions.
