Yes, i re installed the package and was able to reproduce the error pretty fast, here the whole stack trace(package being the source of the issue confirmed): Jul 25 17:38:12 arch-workstation kernel: BUG: kernel NULL pointer dereference, address: 00000000000002b4 Jul 25 17:38:12 arch-workstation kernel: #PF: supervisor read access in kernel mode Jul 25 17:38:12 arch-workstation kernel: #PF: error_code(0x0000) - not-present page Jul 25 17:38:12 arch-workstation kernel: PGD 0 P4D 0 Jul 25 17:38:12 arch-workstation kernel: Oops: 0000 [#1] PREEMPT SMP PTI Jul 25 17:38:12 arch-workstation kernel: CPU: 3 PID: 296 Comm: kworker/u24:4 Not tainted 5.2.2-arch1-1-ARCH #1 Jul 25 17:38:12 arch-workstation kernel: Hardware name: Micro-Star International Co., Ltd.
