This crashes on my PC right after opening! (Win 10 19045.3693) Any solution, plz? reinstalling did not work. Thanks


Since updating Dev to 121.0.2256.2 the browser freezes when you select text within a text form field (like the one I'm typing in right now) and try to select more/less with the blue sliders. 

This bug appears on the latest Canary builds as well.

The last couple Dev drops the PDF does not print or save to pdf. As soon as I select print I get an print screen and busy indication.

Happens on 2 Gentoo systems.

In the journal:

Microsoft-edge-dev.desktop[2216]: [2209:2209:1210/173837.530417:ERROR:CONSOLE(15)] "This document requires 'TrustedScript' assignment.", source: edge://print/print-preview.bundle.js (15)
microsoft-edge-dev.desktop[2216]: [2209:2209:1210/] Initiated PrintPreviewHandler::HandleGetInitialSettings()

Page printing is broken.
ctl-P brings up the print screen but the Web page pane is in an endless wait spin.
Note: regular MsEdge does not have this issue:
MsEdge Version 120.0.2210.61
MsEdgeDev Version 121.0.2256.2
I am getting STATUS_ACCESS_VIOLATION just by opening NTP on Windows.

On linux, I'm getting SIGBUS (7) on github and arstechnica.
Looks like DEV ver 121.0.2277.4
fixed this problem
as well as the "Save as PDF" problem.
Opps, by "this problem", I meant the ctl-P not working.
Version 121.0.2277.4 fixed the print problem on my Linux systems.
