1, the script does not support the current PS version: the script is developed for a specific version of software, and using a script incompatible with the current PS version will cause the script to fail to run normally.
2. The script is not placed in the correct position: Only when it is placed in a specific folder can the slimming script be recognized and executed. Be sure to put the slimming steps into the folder named "Scripts" under the Photoshop installation directory correctly, and ensure that the name and format meet the requirements.
3. Software or other programs are interfering with the running process: Running multiple operating system processes that conflict with each other and compete for resources at the same time will lead to functional failure, including calling dependent programs/libraries and other resources for slimming operation. Close all related programs, and try to restart Photoshop and run slimming again to get better results.
