shipout does not produce PDF when settings.render is nonzero

[bariserkus]

I have freshly installed Windows 11 and TeXLive 2025. I did not install Asymptote or GS seperately.

The shipout command in the following MWE does not produce PDF when the render setting is nonzero (the MWE is taken from the "An Asymptote tutorial" by Charles Staats III (2022):

settings.outformat="pdf";
settings.prc=false;
settings.render=1; //shipout does not work when this value is not zero, works fine when it is zero
import graph3;
size(4cm,0);
path3 myarc = rotate(18,Z) * Arc(c=O,
normal=X, v1=-Z, v2=Z, n=10);
surface backHemisphere =
surface(myarc, angle1=0,
angle2=180, c=O, axis=Z, n=10);
surface frontHemisphere = surface(myarc, angle1=180,
angle2=360, c=O, axis=Z, n=10);
draw(backHemisphere, surfacepen=material(white+opacity(0.8),
emissivepen=0.1*white), meshpen=gray(0.4));
draw(O--X, blue+linewidth(1pt));
draw(frontHemisphere, surfacepen=material(white+opacity(0.8),
emissivepen=0.1*white), meshpen=gray(0.4));
shipout(scale(4.0)*currentpicture.fit());

Executing the asy.exe on the file produces the following files:

testasy+0.eps
texput.log
texput.aux

The texput.log file is as follows:

The file testasy+0.eps can be deleted, but the files texput.log and texput.aux cannot be deleted. The task manager shows two asy.exe and one latex.exe processes that continue running on the background. Upon ending the latex.exe process, these two files can be deleted.

The following MWE, which is also taken from the same tutorial also does not work when settings.render is nonzero:

settings.outformat="pdf";
settings.render=1;
settings.prc = false;
import three;
size(1cm,0);
draw((0,0,0) -- (1,1,1),
linewidth(2pt));
shipout(scale(4.0) * currentpicture.fit());

[bariserkus]

I have tried earlier versions of Asymptote and its seems like the problem starts with version 2.90. The shipout does infact work for version 2.89. I have the latest version of TeXLive, but renamed the asy.exe in TeXLive and placed the path of installed Asymptote version 2.89 before the path of TeXLive in Windows settings.

[bariserkus]

Any comment on this issue?
