Cause: the operating system is 64-bit, but the released program references some 32-bit DDL, so there is a compatibility problem.
Solution 1: If it is a 64-bit machine, IIS -- application pool -- advanced settings -- enable 32-bit application: True.
Solution 2: Modify project properties-generate-Target Platform (for example, x86 \ x64)
