During sitefinity version Upgrade to 14.1 facing issue "Could not find a part of the path '...\AjaxControlToolkit.3.0.20820.0'"

[Softway]

I am writing to raise an issue regarding a problem I encountered while upgrading our Sitefinity instance. We recently initiated an upgrade process to the latest version of Sitefinity, and we've encountered an issue related to the AjaxControlToolkit path not being found.

Despite following the standard upgrade procedure and ensuring that all necessary components and dependencies were properly migrated, we consistently encounter a "Could not find a part of the path '...\AjaxControlToolkit.3.0.20820.0'" error when attempting to use the AjaxControlToolkit features. The AjaxControlToolkit Package is present in the package folder but it is unable to locate it.

1. • Previous Sitefinity Version: 11.0.6701
   • Target Sitefinity Version: 14.1.7800
   • AjaxControlToolkit Version: 3.0.20820.0

2. Error Details:

   • Error Message: "Could not find a part of the path'...\AjaxControlToolkit.3.0.20820.0"

This happens when i try to upgrade all the process happens seemlessly only this creates the issue please provide the solution.

And after the fail upgrade it's not even rollbacking the updates.
