Beta 1.6.14 causes connection issues with War Thunder and possibly for all other apps

[Zer0Key]

What happened:
War Thunder reports connection issues to game servers and heavy packet loss.
After a failed attempt to join a match with a "connection error", a second attempt will succeed but with heavy packet loss of up to 60% and ping fluctuations of >50ms.
Shutting down portmaster resolves the issue.

What did you expect to happen?:
No connection issues or packet loss.

How did you reproduce it?:
Launch the game and attempt to play a match.

Debug Information:

War Thunder Portmaster App debug.md All instances of public facing IP were replaced by 127.0.0.1

Portmaster Debug.md

Other info:
This issue possibly affects all connections but I don't have the technical knowledge to verify this suspicion. However, I've run into weird delayed and failed connections with multiple websites since switching to the Beta channel. Specifically speed tests will randomly fail with connection errors or will produce wildly varying results with re-tests. All of which disappears if I shut down portmaster.
Could be related to #1141

Re-tested with Beta14, issue persists.

I'm having the same issue with Eternal Return (Unity-based Battle Royale - AOS Game), try to make a multiplayer match in the game and when I try to make a successful match on the server, Portmaster blocks it.

Issue persists in 1.6.23
Would love to post the logs but the "copy debug info" button doesn't work.

I think that another problematic application may be https://github.com/rustdesk/rustdesk. With the current stable release (v1.6.10), it works flawlessly, however with the beta (tested with v1.6.24 and v1.6.25), there is an error inside RustDesk about being unable to connect to the network. This happens despite allowing the application to connect to the Internet inside Portmaster.

I am sure that the problem is caused by something that has changed in the beta version, because if I downgrade from it to the stable version with the exact same configuration, RustDesk immediately starts working properly again.

Beta v1.6.25 (stuck at connecting):

Stable v1.6.10 (connects with no issues):

What is strange that inside Portmaster itself, there are no blocked connections reported. Also, I've tried allowing all incoming and outcoming network access, disabling all filter lists, etc., but at the end, Portmaster still blocks the connection somehow.

I can find these unexpected logs in the debug information:

Edit:

The issue seems to be gone in Beta v1.6.26.
