Mcreator does'nt go back to 1.14.4

So, I've ne a topic about this before (on another account) but it's been 4 months without any answer. so, I thought I should make another one

So, Before the 2021.2 update, in the workspace settings the update can go back to 1.14.4 (which is what my mod and forge has been) but after the update it can only go back to 1.15 and when I try that, my Minecraft just gives an error message. Please help
