When trying to flash my program, I get an error Log that I do not understand, and that I can't find any information about online

when trying to flash my program, i get this error:

Error in final launch sequence:
 
Failed to execute MI command:
load >>Path<<\\Debug\\>>project_name<<.elf 
 
Error message from debugger back end:
Load failed
Failed to execute MI command:

Error message from debugger back end:

I thought there may be an error in the run configuration, so I created an empty project for the f103rct, and it flashes without problems.

But even after matching the configurations, I get the same error.

to make it even more confusing, the ST-Link utility flashes the .bin file just fine.

In debug option menu, set openOCD instead of stlink gdb server. try to debug with openOCD and post error logs here.

I made a new project and migrated all the code, took some time but now it works.

I still don't know what the exact error was.
