Reading the OP and I have recently had a similar incident.
Tamiya 1/35th scale Brummbar of some age now.
The kit itself is fine, but the tracks, best advice, throw them away, get some real tracks for the kit or risk my own incident.
Whilst putting on the tracks, insanity took hold of me as they failed me for a third time (trying to assemble and put on model). I was supposed to be just kicking around on this kit too. I have since stopped doing 35th scale with much passion especially on my older less thrilling now kits.
The track snapped on the attempt to attach. I LOST it and football tossed it into the wall.
THAT should have killed the kit.
But after a very long cool off period it was picked up and rebuilt.
She claimed it though (think she mentioned that elsewhere). Put it back together with a bit of patience. Although the treads still suck, and the kit likely will never get taken seriously due to how the tracks fit into the drive sprockets about as poorly as I have ever seen on a 35th scale kit.
But I have indeed found it necessary to just say nope, had enough of this portion of the hobby for a while. Fortunately aircraft and ships and armour are all fairly unique to each other. I find aircraft are like cars, need spotless paint jobs, while ships are all about well planned painting stages and incredibly small parts (on 700th scale). Tanks are where I go when I just want to build something.
Ultimately, I call doing figures though, my vacation from the entire hobby option. No airbrush work. You build the whole item, prime it then get out the brushes and just relax with some fine detail work that has nothing to do with masking a canopy, or complicated painting sequence or doing interiors or tracks.
