I was playing Minecraft on a Windows client via PaperMC on an Ubuntu 22.04 when suddenly it crashed out with an unrecoverable Java error. After the system restarted, remote desktop via xrdp, which has worked fine up until now, says "oh no, something has gone wrong" after the xrdp login screen and stops working. I can log in on console just fine. How do I find out what the unexpected problem might be and proceed to fix it?

systemctl status shows that xrdp is running properly:

Apr 30 11:19:58 mc5600 systemd[1]: Starting xrdp daemon...

then i try to connect from the windows client and the status changes to several errors that xrdp_mcs_recv_failed:

That file references, xrdp.pid contains only a simple number, what is its significance and is that the problem?

ok apparently that pid file has nothing to do with the crashes, and it disappears when the service is stopped.

I tried apt purge xrdp, reboot, apt install xrdp but the problem remains.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
