Usually this indicates a problem with the used reset method (software / hardware).
Could you please try the following: Build the project normally once, then open a CLI and execute the command
C:\Users\goran\.platformio\packages\tool-openocd\bin\openocd -d2 -s C:\Users\goran\.platformio\packages\tool-openocd\scripts -f interface/stlink.cfg -c "transport select hla_swd" -f target/stm32l0.cfg -c "reset_config srst_only" -c "program {.pio\build\nucleo_l053r8\firmware.elf} verify reset; shutdown;"
aka the same command as above but with -c "reset_config srst_only" to use a different reset method.
You may also try different values from here.
Once one works it can be put in the platformio.ini with e.g.
upload_flags =
-c
reset_config srst_only
Edit: corrected -c "set reset_config srst_only" to -c "reset_config srst_only" to which should be right
