I've been using KLayout for years without a problem and XSection since 2018. This last week I've found that XSection no longer works for me.
I was running KLayout 0.26.12 (64 bit version) on Windows10 with a .lyp file customised for our CCD process. XSection version was 1.2 and that was fine until last week. We have a few XSection scripts which, according to the windows file properties, have not changed for a couple of years. Last week trying to run XSection suddenly gave this error message and a blank tab.
undefined method 'string to layerinfo' for # in C:/users/rbell/Documents/ccd_with _implants.xs:9
I've tried updating to KLayout 0.27.4 and this still fails but with a longer, and to me completely incomprehensible, error message. I've also updated XSection to 1.4 which didn't help either.
A colleague can run the same XSection script without errors using KLayout 0.25.3.
The issue persists for several .gds files and different .lyp files.
Rolling back KLayout to 0.26.12 did not solve the issue.
I tried a clean install on a different laptop and the problem remains the same.
Any advice welcome!
