Fatal Error when using CMU fonts with XeLaTeX

I just tried to re-compile the documentation file for the russian-babel package with XeLaTeX. The source file russianb.dtx was last modified in January 2017 (https://www.ctan.org/pkg/babel-russian) and then compilation always was successful. But now I got a compilation error. As short investigation revealed that the CMU font is the cause of the problem, as the following example demonstrates.

documentclass{article}
usepackage{fontspec}
defaultfontfeatures{Ligatures={TeX}}
%setmainfont{STIX Two}[
%    UprightFont={* Math},
%    %UprightFont={* Text},
%    ItalicFont={* Text Italic},
%    BoldFont={* Text Bold},
%    BoldItalicFont={* Text Bold Italic},
%]
    setmainfont{CMU Serif}
    setsansfont{CMU Sans Serif}
    setmonofont{CMU Typewriter Text}
    
usepackage[russian,english]{babel}

begin{document}

English
textsf{English}
texttt{English}

selectlanguage{russian}
Русский
textsf{Русский}
texttt{Русский}
end{document}

Compilation terminated with the following error:

dvipdfmx:fatal: This font using the "seac" command for accented characters...

No output PDF file written.
 )
Error 1 (driver return code) generating output;
file test-CMU.pdf may not be valid.

So it can be guessed that the error is caused by some recent changes in XeLaTeX executables. Can someone help to solve this problem? Note however that the compilation succeeds if CMU fonts is substituted with STIX Two fonts.
