I/O error in writing file

in my previous runs, I didn't see these errors I have no clue how to address this, any feedback would be deeply appreciated

I noticed that there's a new file called

new.gds

should I use it instead of the

sky130_sram_1kbyte_1rw1r_32x256_8.gds

?

thank you Prof. Guthaus! the latest 1kb sram works!
