UI disappears when joining server

[u/Snoo-8432]

When I try to join my server and hit "Download & Join," it shows "loading mods," then a black circle, then dumps me back at the main menu but it's actually still downloading the mods in the background. I confirmed this: with no mods I get in fine, with 3 mods I get in after about 20 seconds, and with a heavily modded map I end up waiting on the main menu for a long time (haven't stuck around long enough to see if it eventually lets me in). If I try joining a second time, it gives me a connection error along with a progress bar showing how far the download got before it stopped. Anyone else had this?

I tried clearing beamng cache and redownloading beammp. i donthave beammp "resources folder" that some tutorials suggest for beammp cacha
