you could try to delete processing  
and download 3.5.3 and install again,  
but need to delete the settings directory also  
c:\users\ \< you \>???\processing\ where also preferences.txt is  
//  
not delete your sketchbook dir.  
//  
and try the update while in english language menu???

Just a guess: you could try out v3.4 just for updating libraries: 😳  
[Download.Processing.org/processing-3.4-windows64.zip](http://Download.Processing.org/processing-3.4-windows64.zip)

Also consider uncompressing the “processing-3.4-windows64.zip” in your “%HOMEPATH%\Documents” folder or some other place away from the OS’s system folders. 🤖
