Can 'Em All: Freezer Perk Kills the Game (Workarounds)
Short answer
No confirmed fix yet. Players suggest: It's making me play the game a lot less and would be nice if the devs fixed it.
The problem
Freezer perk prevents the truck from spawning more than once, after a few rounds. I can only reset it by exiting the game. Because I had enough points on my first prestige I bought freezer perk first and now the game is unplayable.
What players suggest
You have to restart the game after getting freezer. It's a bug AFAICT. I usually do 1-3 runs then the trucks get buggy and I restart. It's making me play the game a lot less and would be nice if the devs fixed it.
Suggested fix (unconfirmed): Restart the game or exit to the main menu and reopen your save. If that fails, check your C drive for available memory space to ensure the game can create a new save.
Suggested fix (unconfirmed): Disable Smart App Control in your Windows security settings, or add an exclusion for the game's folder. Alternatively, check for a pending Steam update to download the newly signed files.
