If only there was a way for the game to continue past 275,760 AD, perhaps until the end of the universe, and beyond. (Date would need to be stored as just the year, more eras would need to be added, and maybe a second layer of prestige at 10^100 years from now)

Dates are limited to 100,000,000 days before or after the epoch of 1 January 1970 AD 00:00:00 UTC for precision reasons. You seem to be hitting this future limit (275760 AD), causing your date to stop increasing.

The dates stop earlier than that because adding the time per game tick to the current date goes past the limit.

Currently using Chrome 79.0.3945.130 (Official Build) (32-bit) on Windows 7 (Build 7600), still gives the same error. Does that have to do with unsupported video card?

Game crashes on start - TypeError: Cannot read property 'getParameter' of undefined. Why?

Randomly, instead of generating an image, it instead generates the following error:
