ER7206 v1.0 crashes when disabling an active OpenVPN VPN profile
Setup
Router:
Main LAN switch:
Cisco SG200-26, FW: 1.4.11.5
PoE Switch for access points:
1 x EAP235-Wall(EU) v1.0, FW: 3.1.0 Build 20210721 Rel. 46004
Miscellaneous:
The usual, servers, some networked speakers, UPS, NAS etc etc.
Network
A basic setup with one router, a main switch patched out to the house, a PoE switch that supplies three access points.
Main switch port "WAN/LAN2" of router
PoE switch port "LAN1" of router
Controller port "LAN2" of router
Divided into two three segments, LAN (1), PrivateWifi (20) and AnnexetLan (30), shown below with Cisco symbols mostly...
VPN:
Client-to-Site VPN, VPN Client - OpenVPN Certificate+Account
Local network: PrivateWifi
Wan: WAN
Problem:
When disabling the VPN connection either from the overview table or from unchecking the "Status: Enabled"-checkbox inside "Edit VPN policy", the router crashes and restarts. All networks goes down, and when coming back up again the controller warns that the WAN of the router is down and " The configurations of device RTR-Techroom-ER7206 are different from the configurations from the controller. "
After adopting it again everything kicks back online.
This does not consistently happen, but in about 80% of the cases.
The VPN in itself works just fine when connected, and enabling it never causes a crash. Just disabling it.

Is there any more specific logs I can get out of the devices to see what causes these crashes?
Can TP-Link help me out, should I return the router for another one, or is it a firmware bug?
