That's a generic script you use "most of the time"? I'd like to see the exact script that gives the error in Avisynth+. If you don't want to give it, fine, but then I'll leave it to others to try to help.

Also, you've been talking about warpsharp.dll but you have loadplugin lines for both warpsharp.dll and awarpsharp.dll. Try loading only the one you really use.

Finally, make a simple script that just loads warpsharp and see what happens. You need to remove all the other complicating factors. If that works you can start adding stuff back to see what causes the problem.

IMHO, you have a case of filteritis too.
