The phrase "decrypt globalmetadatadat" does not correspond to any known standard command, file name, or widely recognized tool.
Without that, it's impossible to give a decryption method or output.
Common encryption methods include simple XOR operations, ROT shifts, or custom schemes used by major engines like those from miHoYo. Typical Reverse Engineering Workflow decrypt globalmetadatadat
A standard, unencrypted global-metadata.dat file always starts with the "Magic" hex signature: AF 1B B1 FA. If you see these bytes: The file is not encrypted.
