build error during archiver, filename mixed with path without slashes

[PerennialNovice]

I have a somewhat larger project (in sloeber) and am in the process of porting from AVR to STM32
Now I ran into a problem I think might be toolchain related:

build runs through fine, only after the archiver step it fails with a strange message

Build might be incomplete 

it seems it is looking for a file named .corecorestm32usbhidusbd_hid_composite.c.o which resembles a lot the first file with path .\core\core\stm32\usb\hid\usbd_hid_composite.c.o

maybe this is a slash/backslash - problem?

This is an issue with Slober.

All right, thanks for the very quick reaction !
I'll reach out to the sloeber team then
