Code in SystemInit() tends to set SCB->VTOR
Check the build address in the linker script is correct.
Use a debugger, step the transition, understand what's "not working"

It's like if there was an uncompatilbility between two files from different compilers.
If I remove "SCB->VTOR" it doesn't change anything...
Is it possible, for example to add a short program in the STMCube "bootloader" soft (adress 0x08033C00) so I can test if it work and try to compare ? (hard to learn a new way of writing code...)

Nobody can answer ? is it really possible to jump to an application , made with other compiler, or did the
compilation made includes a specific area that would not allow it ?
I tried this too but it doesn't change anything (soft is "lost"):
#define ApplicationAddress 0x08033C00
typedef void (*pFunction)(void);
uint32_t JumpAddress = *(__IO uint32_t*) (ApplicationAddress + 4);
pFunction Jump_To_Boot = (pFunction) JumpAddress;
__set_MSP(*(__IO uint32_t*) ApplicationAddress);
Jump_To_Boot();
