Unable to set as input method (continuous crashes)

[2011]

Describe the bug
Hacker's Keyboard crashes immediately (and repeatedly when attempting to select as input method).

To Reproduce
Steps to reproduce the behavior:

1. In either the Hacker's Keyboard application or Settings, attempt to set Hacker's Keyboard as the input method.
2. Hacker's Keyboard crashes immediately, and continues to crash as it keeps attempting to restart.

Expected behavior
I expect it to run. :)

Smartphone (please complete the following information):

• Device: 905X3 television box
• OS: Android 9 based custom ROM)
• App version 1.41.1

Additional context
This worked find on the device until a relatively minor update to the ROM.

In the logs, this pretty much keeps repeating over and over (until I force stopped Hacker's Keyboard):

Given the lack of maintenace on this project, I hope that someone can suggest a solution that does not involve installing a non-existient newer version. :)

[TPS]

Odds are, the next "relatively minor update to the ROM" is more likely to fix this than any HK update.
