I updated a signature on a couple of check templates, tested it on one workstation and it works without issue. Went to another workstation to confirm the form is updated correctly and I received the following error when going into Common Information / Maintenance / CI Setup / Set up Forms (I was logged in as myself, a System Admin):

I then had the team member log in and try to run a test check on this same workstation and this error showed:

Then I went ahead and tried the CrystalConfigLaunch (run as admin), re-opened Sage and tried printing another check with the same result.
Why is this happening? This is not a new workstation, this team member has had no issues printing previously and the only change was the signature to the check.
What do I need to do to fix this?
