IRIS documentation on backup and restore mentions this for the contents of the snapshot:

"The snapshot is typically a snapshot of all file systems in use by the system. At a minimum, this includes all directories used by the InterSystems IRIS database in any way, such as the installation directory, database directories, journal and alternate journal directories, WIJ directory, and any directory containing external files used by the system." (https://docs.intersystems.com/iris20253/csp/docbook/DocBook.UI.Page.cls…)

As @AlexanderPettitt said, the target instance needs to be cleanly shutdown. The snapshot needs to include everything IRIS expects to use; I'm not certain about what is included in the snapshot from your post.  

MISMATCH.WIJ is described here: https://docs.intersystems.com/iris20253/csp/docbook/DocBook.UI.Page.cls?KEY=GCDI_wij#GCDI_wij_recover_compare

If you are comparing the IRIS.WIJ from the target against the contents of the databases from the source (or vice versa) you will get mismatches. If you take the wrong action, you will affect the integrity of the data.  The specific details of this are important: such as how the snapshot was taken, what mounting an svol means, and whether or not you actually have some other problem beyond how the backup was taken.

This is a situation where the WRC can help.  I'd suggest starting there.

Stack Overflow discussion points to a missing or incompatible .NET Framework version, see;

Also,IRISSECURESTARTA is an 8-bit function, you might need one of the Unicode versions instead.
