With more than 50 players is almost a sure crash.
I cannot reproduce. Or at least none of my 20 attempts with 50 players crashed.
This error happens often to me since I started testing v3.0 (it has happened with 3 different revisions of beta2, the last one from yesterday).
I suspected it could be related to my installation, but I have no idea what can it be. I use the same procedure to test S2_6 and had no problems there.
I compiled it from clean folder (no old files), but I do have other mods installed in .freeciv folder.
What was your configure command line?
./autogen.sh --enable-client=all --disable-nls --enable-debug
(disable-nls allows me to test it in english, so it is easier to report bugs)
In order to be able to compile freeciv, I needed to install python-is-python3, else python3 was not recognized as installed by configure (I'm not sure if relevant).
Once the game is created, I have been able to play several ai games during 200 or 300 turns without other problems.

Ticket details:
I'm testing 3.0.0-beta2+ (compiled in kubuntu 20.04, up to date)
When I try to start a new game from the client, it sometimes (looks random) get an error from the server, and goes back to the initial menu (welcome screen).
If I try the same again it uses to end working after 2 or 3 attempts. The more players in the game (or the larger the map, I'm not sure), it seems the higher the chances to fail.
It happens with the default ruleset and default options (civ2civ3, hexemplio), and also when I chose another rulesets or tilesets (I have tried classic and civ2civ3_earth).
These are the backtraces In debug mode (I have tested gtk2 and gtk3.22):
3: Uncompressing of the packet stream failed. The connection will be closed now.
1: Lost connection to server: decoding error.
