• Infinite loops: Issues with .bash_profile include continuous loops that occur when commands are not defined or misconfigured. This type of loops can lead to freezing or crashing of the shell.

• Incorrect environment variables: In this situation, even if the environment variables are set as shown in the example, applications and utilities that use such variables could encounter problems if they include invalid values.

Make re-logging out and back to the platform to execute changes.

Method 3: Utilize A Known Day Repair

If you have to do it manually and you also bear a saved copy of a known working .bash_profile file you made earlier, you can replace the corrupted file with that of copy.
