It seems that the root-cause for this issue is a missing memory-clobber/compiler-barrier in the TX_DISABLE and TX_RESTORE macros (https://github.com/eclipse-threadx/threadx/issues/334#issuecomment-2068839866). I would suggest fixing this issue in the cpu-specific ports instead. There might be other places in the code with possible issues because of this.
