pfsense freezes if wireguard is installed!?

mazec

I had a very difficult time with my Firewall as it was completely freezing up. Nothing works anymore. No Networkservices are working in my network (Routing, DHCP(v4/v6), NAT, DNS), the System cannot be pinged either threw the IP or the Hostname, Devices cannot obtain a IP Adress, and if I am on my Console (VGA) with a keyboard (Currently always plugged in to investigate the issue) nothing is responsive. The "choose a option" was there on top of some successful login sequences but if i press Enter or any other key, nothing happens.
The only way to get around this was to perform a Hardware reset threw the reset key on my Firewall (AMD Ryzen 3 1200, GA-A320M-S2H, a Broadcom 2-Port Networkinterface I salvaged from a old Server, and a Nvidia NVS 295 for primitive graphics output).
I tried everything possible i could imagine:

I checked the logs, but nothing noticeable
observed and let it run but it happend every day or more often which is annoying
performed multiple resets, after which i installed a Backup file.
I tried to uninstall the Wireguard Experimental Package.

The last one seemed to work as my Firewall is now running for a long period of time without freezing.

Jetzt weiß ich nicht ob ich an dem verhalten schuld bin (grobe Fehlkonfiguration) oder ob ich einen Bug-Report schreiben soll.

I used wireguard to obtain a public IPv4 address threw a cheap VPS-Server because I have CG-NAT and aldough I prefer IPv6 it is mandatory to access my home (Nextcloud and stuff) even if I am in a IPv4 only Network.

I am new to bugreports in terms of pfsense and I want to hear the comunity to perform everything right. Or maybe someone else had similar issues he/she/it wants to tell. Everything would be awsome!

Have a nice day everyone!
