Since 120.0.5543.106 version I encounter an issue:

After launching Opera GX, after a few minutes it becomes unstable:

• Opening a new tab does not load the web page,
• But some tabs that are already loaded work (I can even duplicate them and they still work),
• If I try to open, for example, GX Cleaner, GX Control (both located on the left) or Easy Config (on the right), the window opens but the content is not displayed.
• If I close Opera GX and restart it, it works again, but only for a few minutes.

In Windows 11 Task Manager Application, the Opera GX process named: C:\Users\User\AppData\Local\Programs\Opera GX\120.0.5543.106\opera_crashreporter.exe is active, sometimes in multiple instances.

Whether I set the “Automatically send error reports to Opera” option to On or Off, the problem persists.

If I delete all instances of this process, the problem disappears and the tabs that were not loading work again, new tabs work again, everything returns to normal.

Updates: Early Access
Core: 120.0.5543.106
System: Windows 11 64-bit
Chromium: 135.0.7049.115
