We're currently testing a fix for an issue we're aware some users are encountering where the game crashes post-match. To gain access to this fix you would need to move onto our public beta branch.
It’s entirely opt-in, the only thing to bear in mind is that it will be later code, (say 20.2.1 rather than 20.2.0). Your save game should be compatible between both, but the fix is only available in 20.2.1 for now.
We would always recommend backing up any save games prior to joining the pub
