Hi @ChrisI,
i suggest a antivirus program. I got that error in the past and after excluding my radzen Project Folder all works fine. Somewhere a had read which directory from Radzen should be excluded from Antivirus software... but dont remember where.
Indeed this error could happen due to overzealous antiviral software. Usually the solution is to exclude both Radzen's installation directory (c:\program files\radzen) AND your application directory (it looks to be c:\users\VMWare\Documents)
I've excluded the directories in my Windows Defender but it's still giving the error message. However, I am using a VM without any antivirus software except for Windows Defender. Do I need to exclude the VM directory instead?
