Can't build Release, no hints on error.

Trying to build release but its failing with the only message being the screenshot above. Building debug works, but release has an issue

nrf52833 Segger embedded studio

Wrong ss in last one.
Release:
 
Debug:

I know at least all versions of SES from 6.20 on do not work with the nRF5 SDK. Changes in the build process and compiler resulted in breaking changes in compile time and run time (if it even builds) behavior.

Please use the SES version that the SDK was released with, as noted in its Release Note.

For example, from the Release Note of nRF5 SDK v17.1.0:

The following toolchains/devices have been used for testing and verification:

- ARM: MDK-ARM version 5.25
- GCC: GCC ARM Embedded 9.2020-q2.major
- IAR: IAR Workbench 7.80.4
- SES: SES 5.42a

P.s: Please remember to clean/delete the previous build output before re-building with a different SES version.

I'm not sure which version is correct for me, but I was able to narrow it down to either 4.50 or 5.42a. 
4.50 was giving me an error when I open SES itself. Using 5.42a, it seems to be doing the same thing where it seems to be able to build on second attempt. First attempt yields this error message: 

(i did clean the previous build as you suggested in your other comment.)

Edit: This was on linux btw so I'm not sure why it's looking for a windows file path

This sure is a point to note. The error looks like it is from attempting to start a program in a Windows location.

What is the base of the project you are building? As in your development starting point?  Is it an example from a version of the SDK?
