[tor-relays] Why tor new version having problem's with switching tor.exe file

In the old version of tor (less than 8.0) i could download the source code and recompile it( change the number of nodes for example) and create a new tor.exe file and switch it with the tor.exefile, that create with tor installation. but now, in the new version of tor the 8.0, and above, when im doing that i'm having error- 0xc00007b-which means that i'm working with 32 bit on 64 bit or 64 bit on 32 bit. i found work around way that i can install an old version of tor(less than 8.0 version) do the update to 8.0.2 and then i can change the tor.exe file without any error.

why this thing happens?
