Step 5. Now open the file Event Agenda and check if that solved the problem. If you no longer get the error message, it means Tree It is corrupt. Now we need to find out which business is damaged.

Step 6. First, you need to change the name Old tree back Tree. To do this, click the right mouse button Old tree and select Rename. Now rename it to Tree.

Step 7. Expand Tree. Here you will see a series of planned activities. Now you need to rename the first activity and add ".old" at the end of the name (very similar to step 4). For example, if the first activity is KMSAuto, then right click on it and select Rename. Now rename it to KMSAuto.old.

Step 8. After taking the last step, open Event Agenda and check if the error still appears. If you keep getting the error, remove the “.old” from the activity you renamed in the last step.

Step 9. Now, perform step 7 with the next task and then repeat step 8. Continue doing this with each task, until the error message no longer appears in the Task Scheduler.

And when you don't get the error in Task Scheduler, it means the last task you renamed is the bad one. Now, delete the damaged task by right clicking on it and selecting To remove.
