IllegalAccess Error when trying to print with free versions

[DerLatzer]

Hello,
im trying to print an excel File (.xlsx). I´m using IntelliJ with OpenJDK 18 on Windows 11. When im using Spire.XLS.free or Spire.office.free im getting everytime IllegalAccessError.
i have also tried the repo and dependecy from this post

"Error in Excel converter with openJdk 17" (im not allowed to post links )

and it worked well, but is marked with the valuation warning. I´m clueless what to do and after more than 6 hours in researching, im writing this post now
I hope someone could help me

Edit:
It has nothing to do with Maven. I build a new project without maven and just wrote the code in Main and the same error appears
