此外，如果可能，删除所有 Aspose 产品，然后逐个添加，并尝试识别正在创建此问题的产品。我们将分析您的反馈并分享我们的回应。
Here you mentioned that you were using Aspose trial jar. Were you using same versions i.e. aspose-words-21.6.0.jar, aspose-slides-21.5.jar, aspose-cells-21.5.jar?
If no please share which version were you using when the application was working fine.
If the same versions were used, then you just added the license to avoid the trial version warnings during the processing. Is it right? Please share your response.
We want you to revert the application to the previous stage where it was working fine and then share the complete steps which are performed to update your application and get this error. All the version details and license implementation details are required.
Also if possible, remove all the Aspose products and then add one by one and try to identify the product that is creating this issue. We will analyze your feedback and share our responses.
