I had a similar problem.
I contacted support.
It took about 2 months, I got a hot fix.
Applications created with Delphi and C ++ Builder are likely to occur.
The cause is the influence of Win10 1703 specification change.
It seems to be a problem with TLS (Thread Local Strage) at VOS.
I understood that my app works on Windows10 ver.1709 too, If I can get this special fix. Immediately, I will request a support ticket.
Is this problem fixed on Win10 ver.1803?
In win10 1803 ThinApp 5.2.3 It is no good at all.
I want to release the corresponding version as soon as possible.
