[MCreator 1.8.1] ANY of my mcr files failing ALL MOD imports, and also cannot build after manual importing

I have been asking this question I think over and over, and yet, no reponse, only messages that SEEM to maybe fix other people's and I's issues/issue, but really do absolutely nothing, just like the solver (Questionable) just tries their extreme hardest to AVOID solving the problem at hand!

I'm pretty sure I have set MCreator up correctly, all I am trying to do is make it so that I can keep on moving through new MCreator Versions, and still just develop my single mod, but no!: THIS HAS TO HAPPEN:

And yes, last time when I tried (On MCreator 1.8.0) to import my mcr mod file from the previous 1.12.2 Version MCreator version, it would be stuck FOREVER on LOADING MODS.

I could NEVER fix this EVER, even if I waited 3-5 HOURS for it to MAYBE pick up pace, it never did.

BUT NOW it works a little but more, but yea, IT WOULD FAIL, but now with an ACTUAL ERROR! All it says, as I click through ALL OF MY MOD'S ELEMENTS ERRORING, is that it couldn't import, and the number of added erroring elements!

Please help.
