Welcome at the bug report area, you can report bug reports on the EndeavourOS base system by creating a new subject over here. This area is not intended for reporting bug reports on apps and packages.
Please describe in detail what you were doing on your system accurately and submit a system log with your report.
To do so you can follow the procedures on this wiki:
This oneliner will produce a first allover log and system summary we can use to start investigating in the BUG you will report:
lspci > log.txt && lsusb >> log.txt && journalctl -b -0 >> log.txt && cat log.txt | eos-sendlog
It will create a system summary and boot log and then Pastebin this and gives out a short URL you can post inside your BUG report.
If you encounter a BUG on install process please provide the full installer log:
cat ~/endeavour-install.log | eos-sendlog
It will upload install-log to Pastebin, and gives out a short URL you can post inside your BUG report.
