Recover InnoDB table

Windows Server 2016
MySQL 8.0.23
Recent server crash. I have a complete backup of the server from shortly before the crash. There is one specific table I wish to restore, and so far, have tried the following without success:
1) Copy entire database folder containing the table, as well as files from root of Data folder, and the 'sys' db folder, and the my.ini file. Attempting to start the server with this results in service crash with "Multiple files found for the same tablespace ID"
2) with running service, create new schema, and run create statement for the table. Then discard tablespace, copy idb file, and import tablespace. The last command fails with "Error Code: 1034. Incorrect key file for table 'filedata'; try to repair it"
Any other possible fixes I've found seem to revolve around utilities that require compiling, which I do not know how to do. Option 1) would be the preferred route to get working, as there is other less critical data I would like to recover.
Thanks in advance
