macOS Monterey Beta 3 & Safari 15.0 (17612.1.22.1.4)
issue
In "macOS Monterey Beta 3" sometimes Safari try to restart a page several times and then stops with a white page and notice that cannot load.
Initially I solved instantly from the menu:
Develop -> Disable JavaScript.
Once this done, the page has been opened without problems and now it is reopened even if I reactivated JavaScript.
Attention, since the problem may have been solved after installing "Safari Developer Preview", but don't ask me why... Maybe "Safari Developer Preview" introduced some packages in "Library" also needed for Safari?... I can't say it, but now Safari is always working, even if I open very complex pages.
In any case we could conclude that problems derive from poorly realized WEB pages or from Java version and/or that Apple will have to introduce some control so that Safari can open this pages also.
Note: the issue was reported privately and kindly by

And... I forgot ... I add that Safari now it's very much much much much fast !!! ... Really impressive
