BeamMP keeps crashing

I had another server that i played on with my friend, which worked perfectly fine… no lag, no crashing.
about a week ago, i deleted that server and made a new one.
My friend and I have been playing for a few days and if we spawn too many cars in, the game crashes.
In our old server we could spawn at least 10 cars before we started lagging, but in the server, if there are more than 3 cars in total, we seem to lag and crash.
I dont know if this helps, but we have 81 mods in our new server. (we had like 90 in our old one.)
Any help is very much appreciated.
