Before reporting your issue
- I have confirmed that this issue does not happen when ExplorerPatcher is not installed
- I do not have "register as shell extension" enabled
- I have tried my best to check existing issues
Repro ExplorerPatcher versions
70.3, 70.4
Repro Windows Versions
29634.1000 x64 & ARM64
Third-party tweak software installed
None
Describe the bug
- Install EP 70.4
- Windows 10 (ExplorerPatcher) taskbar aka ep_taskbar is configured to be used by default.
- Observe explorer.exe crashlooping and getting the repeated crashing dialog.
Expected outcome
Desktop and ep_taskbar shows normally and functional.
Actual outcome
explorer.exe crashlooping.
Additional info
This is part of the taskbar ABI changes that were initially introduced in 26xxx.8474, then 28000.2298, and finally landed in Canary/Experimental Future Platforms channel in build 29634.
I will fix this in due time along with making a more robust detection for incompatible taskbar ABIs.
