Hi @Selvam, Raja Priya ,
In my test, I cannot reproduce your problem.
Please perform the following troubleshooting:
- Is it just your account or does this happen to all accounts?
- Does the same happen with other types of files?
- Do other document libraries have the same situation? If there is no problem with other document libraries, you can try to move the file to the document library without problems.
- Clear browser cache, or use browser privacy mode.
- Use another browser, eg: IE, Edge, Google.
