Maybe the new family rebuilt the Sawyer house after Texas Chainsaw 3D explaining its appearance in Texas Chainsaw Massacre (2022)? Kidding of course, but I wish 3D and Leatherface were canon to the original timeline. We already have to accept that the Sawyers can be brought back from death, so it could work pretty well anyway with the Sawyers supposedly being killed in 1973. My explanation will always be that the Illuminati (The Next Generation) keeps bringing them back so that they can keep instilling fear for whatever reason.

The first four films are the same continuity regardless of what some people think. The intro texts should be look at as stories and rumours. Stretch appears in III. The Next Generation refers to two other incidents and then silence for 5 years (matching 1991-1996). Then, of course, Fade's comments about the other movies happening. I suppose you could take his comment about Leatherface being given as many chances as movies that happened could be taken to include Texas Chainsaw 3D, but... well, they were very adamant at that time that the only canon movies were The Texas Chainsaw Massacre, Texas Chainsaw 3D and Leatherface so I guess we just lose out on Bubba's whole backstory (or Jed as it were).
My head-canon:
1965 - Leatherface
1973 - Petals
1973 - The Texas Chainsaw Massacre
1986 - Texas Chainsaw Massacre: Part 2
1991 - Leatherface: Texas Chainsaw Massacre III
1996 - Texas Chainsaw Massacre: The Next Generation
2000 - Jason vs Leatherface #1-3
2012 - Texas Chainsaw 3D
2020 - Texas Chainsaw Massacre
202? - Texas Chainsaw Legacy
