Sitecore Commerce Business Tools doesn't load - sitecore

Question

I'm facing a problem with loading the Sitecore Commerce Business Tools on my local machine. I don't get any error in my browser which you can check on the following screenshoot, but the page is not initialized:
Seems like the operations GetNavigationView() and GetLanguageView() are stuck on getting data, but I couldn't figure out what could be the problem.
As preparation steps, I did the Sitecore Commerce Bootstrap, and Environment Initialization via Postman and everything went ok.
In the CommerceAuthoring_Sc9\wwwroot\config.json I set up the certificate thumbprint and here is what I have in the AppSettings:
"AppSettings": {
...
"SitecoreIdentityServerUrl": "https://localhost:5050",
"AllowedOrigins": [
"https://localhost:4200",
"https://sxa.storefront.com"],
"AntiForgeryEnabled": false,
"UseHttpsInKestrel": true,
"SslPort": 5000,
"SslPfxPath": "wwwroot/localhost.pfx",
"SslPfxPassword": "sitecore"
}
Also in the CommerceAuthoring_Sc9\wwwroot\bootstrap\Global.json I added all the environments I use.
Here you can check some of the errors I noticed in the CommerceAuthoring logs:

I checked some solutions that were already mentioned across the forums but no luck fo far.
I'll very appreciate if you have any advice for me!
Updated
After some time, we got the following error on the UAT env. but I'm not sure if we can do a Commerce Bootstrap there without losing our data:

Also, the storefront item 'CommerceEngineDefaultStorefront' exist in the database that is specified in the PlugIn.Content.PolicySet-1.0.0.json file. I feel some of the json files has invalid params/values or the formatting is wrong, but I couldn't find any lead, furthermore, they haven't been changed recently.
